Markets. Supply Side. Cont…

● Reasons to buy
       ● Multipoint, multi-protocol communications
       ● PQ compliance monitoring
       ● Transient detection

                 IEC 61000-4-7 (2002) :Aliasing
  What is Aliasing?
  ● Aliasing is an effect that causes different continuous signals to become
    indistinguishable (or aliases of one another) when sampled. When this
    happens, the original signal cannot be uniquely reconstructed from the
    sampled signal.

  ● Aliasing is a major concern in power quality analysis because improper
    sampling of the analog signal will cause high-frequency components to be
    aliased with genuine low-frequency ones, and be incorrectly reconstructed.

Aliasing Effect
Wagon Wheel Example

● Optical illusion that occurs in older
  movies when wagon wheels appear to
  be turning backwards.
● Caused by slower frame speed of
  camera relative to the high speed of the
  wagon wheels.

What Causes Aliasing?
   ● Aliasing (or folding) occurs when a signal is sampled at a rate that is insufficient to
     capture the changes in the signal.
   ● Sampling at a lower rates results not only in missing data, but also incorrect re-creation of
     the waveform, leading to faulty analysis.

How do you avoid Aliasing?
   ● The Nyquist Sampling Theorem states that in order to avoid aliasing, the
     sample rate should be at least twice the highest frequency contained in the
     sample

  Sampling Rate

  ● Sample rates are important in adequately representing the original
    signal.
  ● Oversampling the original signal:
        ● Increases the meter’s bandwidth
        ● Reduces metering error
        ● Provides a closer approximation to the original signal

Disturbance direction detection
Confidence Scores
                                              ● Requires a trigger (Sag, Swell or a
                                                Transient) to run the algorithm

                                              ● Then the ION 75/7650 determines the
                                                direction of a disturbance

                                              ● Provides a confidence score and the
                                                direction of the disturbance. All recorded in
                                               the Event Log.

                                              ● While the algorithm for a transient is
                                                running, any further pulses are ignored.

Alarm Setpoint Learning
                                  ● Setpoint Module (65).- Monitors a source with respect to an
                                    absolute threshold and it can evaluate either an over or an under
                                    condition

                                  ● Sag/Swell Module (1).- The Sag/Swell Module learns two
                                    values: a sag limit and a swell limit

                                  ● Disturbance Analyzer (6).- Learns an over-alarm If the pickup
                                    value is greater than 100% of the nominal value at the moment
                                    when learning period is initiated; also, an under-alarm will be
                                    learned if the pickup values is less than 100% of the nominal
                                    value.

                                  ● And Transient Module (6).- Evaluates when transients occur in
                                    the system.

                                  ● All four modules Include the following characteristics:
                                          ● Learn now input

Simple Network Management protocol
(SNMP)

● Some applications as Data Centers and Critical Power require SNMP protocol
  to map (convert) registers or data from the meter in to usable information for the
  different systems.

● This implementation of the ION7650 and 7550 supports read only mode, except
  for the following SNMP related text strings:
       ● System Contact
       ● System Name
       ● System Location


● You can also customize the text on the meter’s MIB (Management Information
  Base) file: ion7x50schneiderMIB.asn.

New communications card. (Field
installations)

● Firmware v350 or higher is required

● The 7550/7650 communications card is not supported on legacy
  meters ION7500 and ION7600.

● The difference is only that the D7 and F1 provide faster Ethernet
  connections (100Base-TX and 100Base-FX rather than 10Base-T and
  10Base-FL).
