Markets. Supply Side. Cont…
● Reasons to buy
● Multipoint, multi-protocol communications
● PQ compliance monitoring
● Transient detection
● Waveform recording sampling rate
● High accuracy revenue metering
● ITC (Instrument Transformer Compensation). Eliminates need to replace
Instrument transformers where accuracy is required
● Transformer losses compensation when the meter is in a different location
than the billing point.

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
● Learn install mode
● Learn duration

Gateway Functionality with Modbus TCP
protocol
● Provides gateway functionality when the Ethernet port and/or modem options
are present
● Modbus Master allows front panel display of real-time parameters from any
downstream Modbus devices.

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.

100 Base TX/FX Connectivity
● New communications cards support 100 Base TX and 100 Base FX
connections
● This will support more network infrastructures

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).
