Power Quality Metering

Compliance Monitoring*

w EN 50160 compliance monitoring

w IEC 61000-4-7 harmonics & inter-harmonics

w IEC 61000-4-15 flicker

w CBEMA/ITIC

w IEEE 519 and IEEE 1159

Waveform Recording

The meters can simultaneously capture all

voltage and current channels.

w Sub-cycle disturbance capture

w Record back-to-back waveforms for up to

several seconds

w Display and compare multiple waveforms in

PEGASYS software

w Record 7 cycles at 256 samples/cycle to 96

cycles at 16 samples/cycle with the 7600 ION

w Record 14 cycles at 128 samples/cycle to 96

cycles at 16 samples/cycle with the 7500 ION

Outage Detection

Setpoints let you detect, record, and report

outages in real-time, including duration, date,

time, and relation to other system conditions.

Out-of-Limit Detection

The meters offer accurate and reliable setpoint

capabilities for the detection, recording, and real-

time reporting of frequency variations, voltage or

current phase imbalances, loss of voltage or

current phase, power factor variations, etc.

Performance Indicators

The units can be configured to meter a wide

range of utility performance indicators, including:

w Total outage time (in seconds)

w Out-of-tolerance duration for total harmonic

distortion, voltage, frequency, power factor

and hundreds of other definable indices

Harmonic Distortion Metering

Complete harmonic distortion metering,

recording and real-time reporting, up to the 63rd

harmonic, (127th for 7600 ION via PEGASYS

software), for all voltage and current inputs.

w Individual harmonics, (including magnitude,

phase and inter-harmonics for the 7600 ION)

w Total even harmonics

w Total odd harmonics

w Total harmonics (even + odd)

w K-factor, Crest factor

Symmetrical Components*

Zero, negative and positive sequences including

phase & magnitude for voltage & current inputs.

Identify harmful voltage & current unbalances in

equipment before they cause damage.

Disturbance Detection

High-speed setpoints allow the reliable detection

and recording of events, sequence-of-events,

and alarm conditions, including magnitude,

duration and equipment status. Waveform

recorders are configurable and can record all

voltage and current inputs simultaneously.

Control the number of pre-event and post-event

cycles recorded. Trigger waveform recording with

events, external inputs, or manual control.

Sag/Swell Detection

The 7500 ION and 7600 ION incorporate a

dedicated sag/swell capture capability that can

be used to analyze the severity and potential

impact of sags and swells.

w Magnitude and duration data suitable for

plotting on voltage tolerance curves

w Per-phase triggers for waveform recording or

control operations

Transient Capture*

w The 7600 ION can detect and record sub-

cycle transients as short as

60 ms @ 65 Hz,

(78 ms @ 50 Hz)

w Analyze transients by plotting them on a

voltage tolerance (e.g. CBEMA) curve using

our PC-based PEGASYS software

Data & Event Recording

The 7600 ION offers 4 MB (up to 8 MB optional)

of nonvolatile memory for waveform, event and

log storage while the 7500 ION is equipped with

1 MB. Memory can be allocated as needed

ensuring important data is never lost.

Load Profiling

The 7600 ION incorporates 640 channels via 40

data recorders, the 7500 ION provides 320

channels via 20 data recorders. Channel

assignments are configurable for historical trend

recording of energy, demand, voltage, current,

power quality, or any other measured parameter.

Trigger recorders based on time interval, calendar

schedule, alarm/event condition, or manually.

High-Speed Data Recording

High-speed “burst” recording (as fast as 1/2-

cycle intervals) stores detailed characteristics of

disturbances or outages. Trigger recording by a

user-defined setpoint, or from external

equipment. Gated recording logs data only during

the critical event so that memory is conserved.

Coincident Min/Max Recording

Log the values of key parameters or equipment

conditions coincident with an extreme condition,

complete with date/time stamping. For example,

record all feeder voltages and currents at the

moment a peak demand condition occurs.

Multiple display formats are available, including bar

graphs with min/max indicators

Displays a complete range of power parameters

Unique vector diagram with magnitude and phase

angle can help reduce installation time
