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:


The following points were inter-alia, discussed:


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♣
♣ Spain


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.


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.


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

• Meeting held at the NER Offices on 14 November 2002:


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

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.

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 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

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

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.


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.


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.


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.


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

• 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.


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.


2.1 IEC TC 11 B Recommendations for Overhead Lines

SABS SC 67E would look at whether they needed to adopt edition 3 of IEC 60268.

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.

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.


5.1 NRS 034

This document, which contains South African methodology, is available on the NRS

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-

• 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

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 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;

20/541/CD and

 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.

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

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

appointed on this committee.

The Telex specification will be circulated and comments should be sent to the work

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

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

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.


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
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.
(December 2002)
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 ( 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
• 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.
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 ( 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
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.
