PROGRESS REPORT ON SABS RELATED COMMITTEES. Report Covering the Period July 2002 up to December 2002. Report for the AMEU Website, and for AMEU Members who request the report. Report on theϖ Electrotechnical Sector Board (SABS SB1): Two Electrotechnical Sector Board meetings were held during the six-month period July 2002 to December 2002. The meeting dates were the following: Thursday 10 October 2002, and Thursday 14 November 2002. • Meeting held at the CSIR on 10 October 2002: REPORT: The following points were inter-alia, discussed: IEC MATTERS a. Draft agenda IEC General Meeting, Beijing (Admin circular C1274A/DA) – for information only The invitation and acceptance of South African hosting the 2005 General Meeting was discussed. b. The election of a new Treasurer for a 3-year term of office (Admin circulars no. 53/AC and 94/AC) South Africa supports Mr Mathias Fünfschilling from Switzerland. c. Election/re-election of five members of the Council Board (Admin circulars 56/AC, 56A/AC and 100/AC) South Africa to support the election of the following nominees: • Dr Ellman • Mr H Kim • Mr Nam Teo • Mr Niechoda • Mr Saarinem d. Election of three members (and alternates) of the Standardization Management Board (SMB) (former Committee of Action) for a 3-year term of office (Admin circulars 55/AC and 96/AC) South Africa to support the election of the following countries: South Africa♣ Korea♣ ♣ Spain REPORT FROM THE JUNE STANDARDS MANAGEMENT BOARDθ MEETING A report on attendance at the June Standards Management Board meeting was tabled by Mr IP Kruger. The committee requested clarification on the voting procedure within the Standards Management Board. It was explained that documents were circulated in advance and that, as far as was possible, much of the discussion took place before the meeting. ELECTROTECHNICALθ SECTOR BOARD MATTERS In some countries clause: Only used when special conditions e.g. climatic, cannot be used to restrict trade. New approach concept proposed by Canada is if deviation put in main text and more clearly dealt with. 2. IEC MASTER PLAN TASK TEAM REPORT BACK a. The Chairman’s term of office to be discussed at the next meeting. c. Electrotechnical Sector Board mandate and the validity of this mandate to be reviewed. • Meeting held at the NER Offices on 14 November 2002: REPORT: Dr. Cliff Johnston informed the meeting that in terms of the original terms of reference, meant that the committee had completed its term and that the time had arrived to assess the situation. During this time the committee had come a long way and had fulfilled the SANC of the IEC part of the mandate very well. The Sector Board had not functioned as had been anticipated in terms of advising the Director: Standards or made much meaningful input to the Electrotechnical Standards Development Division. As the SANC required the democratic election of a National Committee of the IEC, the ETSB should possibly be split:- the current structure become the SANC and a new sector board, in line with other sector boards, be constituted. Members are being nominated in their individual capacity. In other sector boards they are looking for particular expertise within an Industry. The concept of a sector board is not to be fully representative, but to be able to give advice to the Director/Management: Standards SA. After much discussion Dr Johnston undertook to revisit the terms of reference at the next meeting. Chairman’s Term of Office: Dr. Ellman was re-elected as Chairman for the next two-year term with effect from March 2003. IEC Matters: The Chairman provided feed-back on General Meeting of the IEC which took place in Beijing in 2002. On the membership of the Conformity Assessment Board (CAB), it was reported that Mr. Kruger would not be able to continue on the CAB and it was decided that Dr. Johnston would be nominated as the replacement member and that Mr. Vinod Singh would be the Alternate. Secretary of the SANC. Mr Kruger has stepped down as Secretary and Dr. Johnston will in the meantime assume the position of Secretary. Report on the progress ofϖ SABS and NRS Technical Committees: The AMEU serves on twenty-eight SABS Technical Committees and NRS Working Groups, which include the Electrotechnical Sector Board and the SABS Code of Practice – SABS 0480: Quality of Supply Working Group and eight NRS Working Groups. The Technical Committees are the following:- TC 62 Electrical Measurements TC 64 Lighting and Optics SC 64A Lamps and Auxiliaries SC 64C Luminaires TC 66 Electric Cables TC 67 Electrical Distribution Systems and Components SC 67A HV Switchgear SC 67B LV Switchgear SC 67C Electrical Accessories SC 67D Insulators SC 67E Electricity Distribution SC 67F Electrical Installations TC 69 Power Electronics TC 73 Electromagnetic Compatibility SABS – IEC TC 20: Electric Cables and Accessories TC 80 Working Group: ICASA/SABS TC 80: Telecommunications and Broadcasting Standards in South Africa. (SABS 1234 TE – 001) Code of Practice – SABS 0480 : Quality of Supply Working Group: ( Including the Revision of NRS 048 and NER Power Quality Advisory Forum). Electrotechnical Sector Board (SABS SB1) Working Group for SABS 0198: Selection, Handling and Installation of Cables up to 33 kV. NRS Working Group 059: Minimizing Theft of Copper. ( Amendment 1 to NRS 059 was completed in October 2002 ). NRS Working Group 066: MV Insulators ( Published in November 2002 ). NRS Working Group 068: Earth Fault Indicators for Cable Systems ( Note: Spec. was published in Feb. 2002 ). NRS Working Group 071: Remote Metering System ( Note: The first draft is being prepared based on the DLMS User Association Standards that have recently been adopted by the IEC ). NRS Working Group 072: Overhead Fault Path Indicators ( Approved by the ESLC. Will be published shortly ). NRS Working Group 074: Low Voltage Cable Systems for U/G Electrical Distribution. ( Will be based on PIESA 003. PIESA is the Power Institute of East and Southern Africa. NRS 074 will be finalized based on specific SA ESI requirements ). NRS Working Group 018: Fittings and Connections for LV O/H Power Lines Using Aerial Bundled Conductors. ( Note: This Spec. consists of five parts and is being reviewed. Published specifications are reviewed every 5 years to ensure that the information is not outdated and to assess if new information should be added ). NRS Working Group 069: Recovery of Capital Cost. (Note: A contract is to be placed with an external supplier to develop this Spec.). NRS PIESA Working Group: LV Cables (Note: The following specifications were approved. Approved by the AMEU – (Japie de Villiers), in July. PIESA 003 Parts 2 and 3 cover the accessories and application of the low voltage cables. PIESA 002-2 – Fuse Links. It is worth noting that being southern and eastern African utility specifications, the requirements in certain PIESA specifications will be diverse and certain requirements will not be relevant to the SA ESI. This is as a result of the needs and conditions of the other Utilities that have to be considered in the PIEAS specification. In this case the NRS specification on that subject will contain the specific SA requirements. Where the above situation does not apply, the NRS Specification will be a direct adoption of the PIESA specification ). The following Committee Meetings were held during this period. 31 July 2002 SC 67A Report by Evert van Helden - (Leon Fourie) 7 August 2002 SC 64C Report by Fred Grashoff - (Fred Grashoff) 21 August 2002 TC 73 Report by Japie de Villiers - (Japie de Villiers) 28 August 2002 SC 67F Report by Evert vamn Helden – (Greg Brown) 4 September 2002 TC 69 Report by Louis de Wet – (Louis de Wet) 18 September 2002 SC 64A Report by Fred Grashoff – (Fred Grashoff) 9 October 2002 SC 67E Report by Evert van Helden – (Arthur Smith) 23 October 2002 TC 64 Report by Fred Grashoff – (Fred Grashoff) 30 October 2002 TC 67 Report by Evert van Helden – (Evert van Helden) The following Committees and Working Groups are not ordinarily pre-scheduled and operate on an as and when required basis. SABS – IEC TC 20 – Report by Japie de Villiers. TC 80 Working Group (ICASA/SABS TC 80) – Report by Harm Boer. Code of Practice - SABS 0480 - Report by Tony Dold. Working Group for SABS 0198 – No meeting, no report from Japie de Villiers. NRS 059 Working Group - No meeting, no report from Gerrit Teunissen. NB. It needs to be noted that NRS 059 has been approved by the ESLC for publication. However, at the ESLC voting stage, some comments were received on NRS 059 and because of this, the NRS Working Group had to address these comments by means of an amendment. The amendment was published in November 2002. NRS 066 Working Group – No meeting, no report from Japie de Villiers. NRS 068 Working Group – No meeting, no report from Mark Walter. NRS 071 Working Group – No meeting, no report from Kobus van den Berg. NRS 072 Working Group – No meeting, no report from Mark Walter. NRS 074 Working Group – No meeting, no report from Arthur Smith. NRS 018 Working Group – No meeting, no report from Japie de Villiers. NRS 069 Working Group – No meeting, no report from William Dykman NRS PIESA Working Group ( To ensure the ESI’s input ) – No meeting, no report from Japie de Villiers. Summarised versions of the reports are submitted :- • 31 July 2002: SC 67A Meeting : Evert van Helden – (Leon Fourie) This Technical Committee deals with HV Switchgear. The SABS is concerned about the substantial change in the people serving as representatives on the committee. A further concern is the continuity of communication between the international liaison sub committee and this committee. The representatives of the various stakeholders on the sub committee no longer regularly attend the SC 67A meetings. This leads to a situation, which defeats the intention of their representation on these sub committees. The IEC SC 22F meetings are not attended since the SABS is no longer a member of the committee. The published standard has been amended since last year. The relevant NRS specifications have been adopted as ‘SABS 1874 – Metal enclosed ring main units for rated a c voltages above 1 kV’; and ‘SABS 1885 – Metal clad switchgear for rated a c voltages above 1 kV and up to and including 36 kV – General’. A new specification SABS IEC 61958 – High voltage prefabricated switchgear and control gear assemblies, voltage presence indicating systems, has been included. The NRS 006 Specification – Should already have been withdrawn from the published list of Standards. SABS IEC 62271 Part 102 will be added to the list. A concern was raised regarding the proposed SABS 0142 - Part 2 - High Voltage Switchgear Installations. The concern is that the proposed document was not well distributed for comments. Further concerns were raised about the Evaluation Committee which is in fact a Low Voltage Committee and cannot act on behalf of the industry. A further concern is that a high voltage installation standard cannot merely be incorporated in the SABS 0142 Standard. This could lead to a situation where high voltage installations (reticulation and substations) could be included in the certificate of compliance. The Chairman has undertaken to ensure that the process of the document will be more inclusive and if anyone would like to raise any concerns, they are welcome to do so. 7 August 2002: SC 64C Meeting: Fred Grashoff – (Fred Grashoff) This Technical Committee deals with Luminaires. Street Lighting/Floodlighting Luminaires. SABS 1277/8/9 are scheduled for revision. The reason for this is that previously these specifications were exempt from SABS 1464 – Safety of Luminaires Series. Luminaires will now no longer be exempt from the safety requirements as covered in the IEC 60598 Series. The revised SABS specification would also be based on the IEC Specification for Luminaires. The ARP 035 Guidelines will be published as SABS 098-3, Public Lighting. SABS 1777 – Photo-electric Control Units, is due for revision. (BS-5972 is currently under revision). • 21 August 2002: TC 73 Meeting: Japie de Villiers – (Japie de Villiers). This Technical Committee deals with Electromagnetic Compatibility. The meeting, which was the 14th, was held at the SABS in Groenkloof, Pretoria on 21 August 2002. The scope of the committee is given as standardization in the field of electromagnetic compatibility (EMC), which includes emission and immunity and the AMEU has participating membership. Working Group 1 is concerned with Immunity and Emission Standards Testing. This working group did not meet during the past year, however a number of emerging needs was identified and these will receive attention during the course of the coming year. Working Group 4 handles Broadcasting Interference and similarly did not meet in the past year. The Convener of Working Group 5 is Mr. Eric Winter and this Group addresses Human Exposure to Non-ionising Radiation. A new Convener, Mr. Leon du Toit from the Department of Health was selected. No pressing matters are envisaged. Working Group 6 deals with EMC in Telecommunications and is considered the most active group. A number of publications will be adopted as South African specifications in the near future. Working Group 7 is also currently inactive and deals with Immunity of Personal Medical Equipment. International liaisons take place as normal with the following exceptions: • IEC SC 77 A – Low-frequency phenomena (P-membership). Mr. Paul Johnson was elected as the convener. A European document 77A – 381-INF, relating to quality of supply will be made available to TC 73 committee members. • CISPR E and CISPR G have combined and is now called CISPR I. The Chairperson is still Mr. Eric Winter. Prof. H. Reader gave a small presentation requesting TC 73 members to indicate whether enough manpower is available to handle certain aspects related to EMC. It was felt that a combined effort would suffice. A second point raised concerned the inclusion of curricula at tertiary institutions to ensure an adequate supply of technical personnel in future. • 28 August 2002: SC 67F Meeting: Evert van Helden – (Greg Brown). This Technical Committee deals with Electrical Installations. SCOPE AND MEMBERSHIP Due to the variety of the standards falling within the scope of SC67F a fourth group has been introduced into SC67F to accommodate installations above 1 000 volt. INTERNATIONAL LIAISONS A lot of work has taken place internationally on various technical committees with representation from South Africa. A moderate number of the IEC standards produced are referenced in the SABS standards and in some cases adopted as SABS standards. As a result of the inclusion of electrical installations above 1 000 volt in SABS 0142, it has been agreed that South Africa become an observer member of IEC TC99 which deals with electrical installations with voltages above 1000 volt. SABS STANDARDS The revision of SABS 0142-1 (wiring of premises) was approved on 1 November 2001 and made available early in 2002. After the launch of SABS 0142-1 which entailed a road-show throughout the country, a number of complaints and queries were received which resulted in the draft of Amendment 1. The SABS 0142-2 (electrical installations above 1 000 volt) draft which was circulated for comment has received a lot of negative comment and criticism which has resulted in the expansion of the membership of SC 67F and the SABS 0142 Work Group to include experts on medium voltage, hence the delay in publications of the said standard. The SABS 0199 (The Design and Installation of an Earth Electrode) draft document is virtually complete and will be circulated in due course. The SABS 0313 (The Protection of Structures Against Lightning) has been revised and will be circulated as a draft standard. EMERGING NEEDS SABS 0121 (Cathodic Protection of Buried and Submerged Structures) is to be transferred to SC67F and circulated to check its validity. If it is found to be valid, it will be re-affirmed, if not valid, it will be revised. • 4 September 2002: TC 69 Meeting: Louis de Wet. This Technical Committee deals with Power Electronics Of interest to AMEU members are the following: 1 SABS TC 63 – Batteries – The photovoltaic battery specification has been adopted by this committee. 2 The following documents have been published since the previous meeting: 2.1 SABS 1652 Edition 1.03 2.2 SABS 1474, SABS EN 50091-1 and 2, SABS IEC 2040 2.3 SABS IEC 61204 2.4 SABS IEC 61204-3 2.5 SABS IEC 61204-6 3. SABS 0334: Photovoltaic Systems for homes – a series of documents were published by NRS (NRS 052 series), which covered this field. • 18 September 2002 – SC 64A Meeting : Fred Grashoff. This Sub-committee deals with Lamps and Auxiliaries. Report on the proceedings of the 11th meeting held on 18 September 2002 at the SABS. 1. Liaison; Mr C Jonker has resigned from the SABS and a substitute would be determined in conjunction LTL. 2. List of published standards; SABS IEC 60188 High-pressure mercury vapour lamps. Performance specification has been published. 3. Programme of work; SABS 1250 Capacitors, discharge lamps etc.(frozen) programme waiting for IEC 61048. SABS 1266: Ballasts for discharge lamps, amendments to be published shortly. SABS 1888: Traffic signal lamps; final editing stage to be issued soon. SABS IEC 60432 Part 1 and 2: Safety specification for incandescent lamps. Both documents are at the final editing stage- SABS 56 is to be withdrawn soon. 4. General: Lamp holder test failure problem has been identified. The onus is on the purchaser to establish that lamp-holders have been manufactured to the correct compulsory E 27 Standard. Standards: All national standards will in future be published as SANS (South African National Standards). • 9 October 2002 : SC 67E Meeting: Evert van Helden. This Sub-Committee deals with Electricity Distribution. The 11th annual meeting of the above subcommittee was held on 09 October 2002, at the SABS in Pretoria, and was attended by 22 delegates representing the SABS, Eskom, various institutions and equipment suppliers. 1. MEMBERSHIP It was disappointing to note that several of the inactive P-members had not responded to letters sent them and were therefore deleted from the membership list. Furthermore there were some people on the IEC distribution list that were no longer interested and their names would be deleted. 2. PROGRESS MADE BY SABS AND NRS TECHNICAL COMMITTEES 2.1 IEC TC 11 B Recommendations for Overhead Lines SABS SC 67E would look at whether they needed to adopt edition 3 of IEC 60268. 2.2 IEC TC 14 B Power Transformers Part 4 of the IEC 60076-series would be adopted soon. IEC 60214-1 would be circulated to the local committee as soon as it was available. 2.3 IEC SC 15C – Specifications The list of available specifications from this committee would be circulated to the local committee. 2.4 IEC SC 28A – Insulation coordination for LV equipment This committee was renumbered TC 109. 2.5 IEC SC 32 – High-voltage fuses The local committee had adopted IEC 60282 from SC 32A and IEC 60269 from SC 32B. 2.6 IEC SC 32 C – Miniature fuses South Africa had relinquished its membership status on this committee to N-member. 2.7 IEC TC 33 – Power capacitors SABS TC 61 had adopted IEC 60252 from this committee. The standards list this committee would be circulated to SC 67E for information. 2.8 IEC TC 37 – Surge Arresters This committee was working on amendments to some of the IEC 60099-series which would be adopted locally. Part 6 would be adopted immediately. 2.9 IEC SC 37B – Specific components for surge arresters and surge protection devices The entire series of IEC 61643 would be adopted as it became available.IEC TC 38 – Instrument transformers Part 5 of IEC 60044 was still a Publicly Available Specification (PAS), which meant that it had not yet gone through the consensus stage and could not be adopted yet. It would be valid for an initial period of three years. Parts 3, 6 and 8 would be sent out to SC 67E as soon as they became available. 2.10 TC 57 – Power system control and associated communications The Electotechnical Sector Board had suggested that South Africa become P- members of this committee. The committee felt that the activities of TC 57 were more relevant to SABS TC 62. 2.11 IEC TC 73 – Short-circuit currents The IEC 60909-series was available at the SABS library for viewing but would not be adopted. 2.12 IEC TC 78 – Tools for live working The committee was working on edition 2 to IEC 61243. IEC 61482-2, a specification for protective clothing would be sent out to SC 67E for possible adoption. 2.13 IEC TC 96 – Small transformers and reactors and special power transformers and reactors The committee would be deleted from the SPS of SC 67E as it was more related to SABS SC 64A 3. PUBLISHED STANDARDS The following international amendments have been published since the last meeting. 3.1 ARP 026 – Medium-voltage underground distribution systems with low initial cost This document would be reaffirmed for five years. 3.2 SABS 1019 – Standard voltages, current and insulation levels for electricity supply A consolidated edition 2.04 to this standard was approved in November 2001. 3.3 SABS 1029 – Miniature substations The revised standard would replace SABS 1030 and the previous edition of SABS 1029. 3.4 NRS 005 – Distribution transformers- Preferred requirements for application in the electricity supply industry NRS 016 – Electricity distribution – Code of practice for the earthing of Low-voltage distribution systems These two documents had been withdrawn by the NRS after SABS 780 and SABS 0292 had superseded them respectively. 3.5 NRS 037-1 – Telecontrol protocol – Part 1: Telecontrol for stand-alone remote terminal units This document would be moved to SABS TC 62. 4. PROGRAMME OF WORK 4.1 SABS 1934 – Live-working portable equipment for earthing or earthing and short- circuiting – National modifications to international requirements This is a revised version of SABS 1608 and a draft for comment had been sent out to the committee. 4.2 SABS IEC 60282-1 – HV fuses – Part 1: Current-limiting fuses SABS IEC 61643-12 – LV surge protection devices – Part 12: Surge protective devices connected to low-voltage power distribution systems – Selection and application principles The above documents had been sent out as DSS and would be published soon. 4.3 SABS IEC 60099-1 – Surge arresters – Part 1: Non-linear resistor type gapped surge arresters for a.c. systems IEC issued an amendment 1 and soon thereafter, a consolidated edition 1.1. The latter would therefore be adopted. 5. EMERGING NEEDS 5.1 NRS 034 This document, which contains South African methodology, is available on the NRS website. 5.1 Adoption of NRS 034-1 This document will be sent to the SABS technical reviewer to check for suitability as a national standard, to do the necessary editorial changes and to put it in the SABS format and then it would be adopted as a national standard. 5.2 Adoption NRS 048 A WG consisting of members of the NRS WG, NER and large users of electricity will be formed under the leadership of Messrs P Johnson and R Kock to review NRS 048- 2. Other parts of NRS 048 would be considered later. 5.3 SABS IEC 61243-series to be declared compulsory and, SABS IEC 61481 to be amended to be a mark spec IEC 61243, IEC 61481 and IEC 61230 will be proposed as a compulsory specification. 5.4 Earthing of substations 5.5 Revision of SABS 780 6. GENERAL 6.1 As a result of the SQAM review, all standards are going to be renamed. A list of the old and new standards numbers will be published in the Government Gazette. • 23 October 2002 : TC 64 Meeting : Fred Grashoff. The Technical Committee deals with Lighting and Optics and is the umbrella body for the 64 SCs and only meets when required and specifically when SCs experience problems. As there were no urgent requirements, the meeting scheduled for 23 October 2002 was cancelled. • 30 October 2002: TC 67 Meeting: Evert van Helden. This Technical Committee is the umbrella body for the 67 SCs and only meets when required and specifically when the SCs experience problems. As there were no urgent requirements, conflicts or appeals from any of the six subcommittees, the meeting of TC 67 scheduled for 30 October 2002, was cancelled. The SABS however issued a directive on the future developments of national standards and a directive was received from Mr. Adolf Claasen, Manager: Electrotechnical Standards, who wrote as follows: “We are writing to update you on some important new developments in the way we will be developing national standards in the future. The Standards Division of the SABS has changed its name and will henceforth develop and publish standards under the banner of Standards South Africa, to distinguish ourselves from the identity of our parent organization, SABS. This identity change was identified as necessary during the recent review of South Africa's SQAM (Standards, Quality Assurance, Accreditation and Legal Metrology) infrastructure commissioned by the Department of Trade and Industry, and is part of an ongoing implementation programme of transformation deemed necessary to bring us closer to our stakeholders. All of our national standards are being re-designated as SANS (South African National Standard) standards, as opposed to SABS standards. While this will necessitate some numbering changes of existing standards, the change is a necessary one, and any inconvenience to users will be kept to a minimum. The new numbering system, as a single series, will also be much simpler and clearer than before. Old standards numbers will not fall away immediately, but will run in parallel with the new numbering system for at least 5 years during which time both numbers will be legally valid. The physical renumbering and changing of the "look and feel" of around 5000 standards is a mammoth task. For some time, therefore, it will be necessary for us to continue to deliver standards that bear the SABS numbers and that include references to SABS-numbered standards. Please rest assured that these standards are just as valid as the newer, SANS-numbered standards that will eventually take their place over the next 5 years. A full list of the numbering changes is being published shortly in the Government Gazette, and thereafter, will be available for consultation at our offices and on the website. It is important for standards users to note that any reference to a SABS standard, in any context or forum, will be deemed to be a reference to the corresponding SANS standard in the list referred to above, and vice versa. All existing standards projects will also now have, as their ultimate deliverables, SANS standards as opposed to SABS standards. Our project documentation will change to reflect this. Should you have any concerns about the changes and how they affect you, please email us on firstname.lastname@example.org or contact me personally.” • 8 August 2002 : SABS IEC TC20 Meeting : Japie de Villiers. This Technical Committee deals with Electric Cables. A report was tabled at the meeting and debated, with the following resolutions: To vote in favour of the following IEC documents which were received; 20/539/CD 20/540/CD 20/541/CD and 20/542/CD. That it be assumed (pending Eskom’s response), that IEC documents 20/545/CD and 20/546/CD will also be voted for favourably. That Mike Lang’s comment to Anthony Falconer on 4 August 2002, concerning the IEC Flame Propagation Test, be supported. • 15 August 2002 and 14 November 2002: SABS/ICASA TC 80 Committee Meeting: Harm Boer. This Technical Committee deals with Telecommunication Regulatory Standards. Introduction The committee meetings are about the setting up of South African telecommunication regulatory standards (to be promulgated by the Minister of Communications), and over and above ICASA, SABS, the AMEU and certain equipment suppliers and consultants, the following organisations are participating or observational members: Consumer Electronics Association; CSIR; EMC Assist; Eskom; Eskom Enterprises; Electronics and Telecommunications Industries Association; Information Technology Association; M-net; National Association of Broadcasters; Professional Mobile Radio Association; SABC, SA Cellular Communication Association; SAPS; SA Tetra Association; Sentech, Telkom; Transtel and Vodacom. The following Work Groups have been in existence before the sixth meeting of the TC80 committee: Work Group 1: ISDN, xDSL and digital leased line related standards; Work Group 2: Radio related standards (including cordless telephony); Work Group 3: Analogue terminal related standards; Work Group 4: PABX and VPN/PISN related standards; Work Group 5: Broadcasting; Work Group 6: EMC in telecommunications The AMEU has observer status in the TC80 Committee, and normally two delegates attend these meetings. This report covers the Sixth and Seventh meetings of the Committee The 6th meeting of the TC80 Committee This meeting took place on August 15, 2002. Work is being done on the ISDN and ADSL subscriber interfaces and a so – called microfilter specification. The legality of cell blocking device are under discussion. The way ahead regarding microwave and bluetooth standards are considered. It was pointed out that although radio equipment had to be type approved according to the regulations, no such regulation exists for broadcasting equipment. Quite a lot of international standards were adopted for local use, to be approved by the Minister. Furthermore, at the proposal of Eskom, a new Work Group was instituted to deal with Power Line Communications, as both Tshwane Municipality and Eskom were busy with trials in this regard. The 7th meeting of the TC80 Committee This meeting took place on November 14, 2002. The members were notified that all the SABS standards would in future be known as SANS standards (SA National Standard). It will, for the time being, be legal to refer to any of the two. Furthermore, the numbering scheme has been rivisited and details of the changes are available in Government Notice 1373 as appearing in the Government Gazette 24002. It was decided that Quality of Supply regarding fixed line operators should not be regulated. An Ad Hoc committee was compiled to look into the possible regulation of electric fencing regarding EMC and safety. Both AMEU members present have also been appointed on this committee. The Telex specification will be circulated and comments should be sent to the work group within three weeks after circulation Work Group 7 regarding Power Line Communications must liase with Work Group 6 in connection with the EMC implications of PLC equipment. It was further decided that when ETSI-standards were locally accepted, the SABS and ICASA websites should link to the ETSI website where these standards can be downloaded. The reports of the different work groups were approved. Most of them are very busy looking into international standards, their appropriateness for the local conditions, circumstances and systems, and then putting them up for voting, whereafter the proposed standards are sent to ICASA for approval by the Minister of Communications. So far, no meetings of Work Group 7 (PLC) did take place. The names of Mr E. Winter (EMC Assist) and J. Botha (Telkom) were added to the work group. Mr C. Naidoo of Eskom is the Convenor of the work group. Summary Electricity undertakings are mainly users of the radio spectrum, and their voice is important to protect their current and future communication systems. However, with some undertakings moving into the data communications market it is gladdening to see that the committee is prepared to include the AMEU members into their work groups, as recently happened with Work Group 7 (PLC) and now also with the Ad Hoc Work Group for Electric Fencing. However, the two members involved are not necessarily aware of all the communication or EMC issues of local authorities and would like to invite any electricity undertaking official to contact the AMEU Representatives on this TC regarding this. • SABS 0480 Including Revision of NRS 048 Meeting : Tony Dold. This SABS Working Group deals with Quality of Supply. This is the latest report covering the activities of the NRS 048 Working Group on Power Quality and the NER Power Quality Advisory Committee. Received December 2002. It is important to note that the NER is expected to start the implementation process of the NER Directive on Power Quality early in the new calendar year which will need licensees’ special attention in order that they can make submissions by the middle of the year according to the programme presented to the NER PQ Advisory Committee on 21 November. UPDATE REPORT : NRS 048 : QUALITY OF SUPPLY STANDARDS (December 2002) 1.0 NRS 048 WORKING GROUP 1.1 NRS 048: Part 2 (Minimum Standards) The Working Group has met on three occasions since September 2002 but the direction has not changed from that given in detail in Mr. Dold’s previous report (June 2002) except to add that the section under Forced Interruptions is now being treated in much the same manner as had been outlined for Voltage Dips. i.e. the prescribed compatibility levels have been eliminated in favour of a utility/customer relationship. These meetings were concerned with the finer points of the document, which, even now, is not complete. The final issues relating to what is now headed ‘Interruptions and Customer Voluntary Load Reduction Events’ is presently being dealt with by correspondence. It is expected that it will be possible to issue a completed draft for voting by the Working Group early in January 2003 and that the document will be considered by the Electricity Suppliers Liaison Committee (ESLC) by the end of March 2003. Thereafter, NRS 048 Parts 1 and 2 will be passed over to Standards South Africa (STANSA) to develop a South African National Standards (SANS) document. As large electricity users have already been involved in the development of the NRS, it is expected that this process will be completed within 6 months after this. 1.2 NRS 048: Part 1 (Glossary of Terms) Some changes have been necessary to this part of the document to provide additional terms and descriptions to complement the changes which have been made to Part 2. It is expected that this will be finalised by the end of January 2003 and be considered by the ESLC at the same time as NRS 048: Part 2. 1.3 NRS 048: Part 3 (Procedures for Measurement and Reporting) Edition 3 of this document is still with SABS (STANSA) for hard-copy publication but was released on the NRS website (www.nrs.eskom.co.za) in August 2002. It is important to note that the National Electricity Regulator presently defines licensees’ minimum monitoring requirements and annual submissions of Q of S performance based on Edition 2 and, whilst it is expected that this will be changed to align with Edition 3, there is currently an anomalous situation. Further, the NER Directive on Power Quality, (covered in Item 2.0 below), which is likely to be implemented in the second part of 2003 will also influence how this is used. The significant changes in this edition are: • The minimum number of sites to be monitored has been prescribed using slightly different site categories but the significant change is that LV network sites have been excluded. • The network categories to be used for medium voltage forced interruption indices have been reduced to 2, with 3 of the previous categories combined into one. • A worked example of the calculation of forced interruption indices has been added for clarity. 2.0 NER POWER QUALITY ADVISORY COMMITTEE Since Mr. Dold’s report in June 2002, there have been three meetings of the above referenced committee: on 17 September, 11 October and 20 November 2002. Again there has been no change in direction from what was covered in some detail in Mr.Dold’s previous report and the primary purpose of these meetings was to discuss the manner in which the NER will expect the Directive on Power Quality to be implemented by licensees. However, there is a need to again highlight the significance of this Directive for all licensees and record that the full document is available on the NER’s website (www.ner.org.za). It can be reported that the licensee members continued to advise the Committee that, as elements of the Directive required resources, which some licensees will not have available, the implementation programme should preferably be delayed until after the establishment of the REDS. The committee has generally been responsive to these concerns but, whilst it is believed the NER will accept a phased programme over several years for a licensee to implement some of the more resource-demanding elements of the Directive, the start date is now scheduled for the middle of 2003. The NER has agreed that the requirements and implications of this Directive will be communicated at workshops around the country before implementation. Attention is drawn to a Paper by R G Koch (Eskom Enterprises), P Balgobind (NER) and E Tshwele (Karabo Engineering) entitled “Development in Power Quality Management in South Africa”, published in the October 2002 edition of Energize which covers the subject, particularly with regards to voltage dips, very comprehensively. To further address the concerns that had been raised, a document was finalised at the last meeting which should be a useful guideline for licensees to develop their Power Quality Management System (PQMS) which is a requirement of the Directive. This guideline covers: • The Contractual Process. At the request of a customer, a licensee will be required to provide a contract which outlines basic power quality commitments, information on the network, indicative quality levels, customer responsibilities, information on the complaints procedures and contact details. This can be a standard contract which simply refers to NRS-048. • The Operational Process. Mechanisms for dealing with customer power quality complaints must be formalised by the licensee. • Managerial Interventions. The licensee must formalise the process to be followed if a customer is not satisfied with first line response. This will include the requirement (as per the Directive) for the customer to submit a Non-Conformance Report (NCR) to the licensee. The NER will only address complaints where the parties fail to reach a resolution following a NCR but the licensee will be required to report to the NER on an annual basis the number of NCRs received. • General Requirements. The implementation of appropriate power quality monitoring, technical investigations and audit mechanisms. • NER Interventions. Submission to and approval by the NER of Power Quality Management Systems. Mediation and arbitration of disputes, periodic auditing, review and publishing of statistics, etc • Typical Implementation Plan and Forms. The licensee will have to indicate the nature of systems to be implemented for the power quality monitoring and the intended programme of implementation. • Model Power Quality Charter. This is also particularly important as it will require the licensee to set down its quality of supply policy, standards to be followed, customers’ rights, customers’ responsibilities and the contact/complaints processes. The programme submitted by the NER at the meeting on 21 November 2002 indicates that there will be workshop meetings/communication with AMEU members and the Executive from 1 January to 30 June 2003 and that returns from licensees will be expected in July 2003. Also, at the last meeting, the NER tabled a document to be used for stakeholder consultation entitled ‘NER Performance Monitoring System (EDPMS)’. This outlines the intention to introduce, by 2004, a system to manage the collection, analysis and reporting of comprehensive performance information for licensees which will be used to support strategic goal setting and economic regulation. The programme shown assumes that REDS will be established by September 2003 which does not appear reasonable at this stage but it is uncertain how one will impact on the other. It is expected that this will be discussed further at the next meeting scheduled for the end of January 2003. End of report. Al Fortmann. Technical Secretary.
