1-2.1 COMPREHENSIVE INFORMATION
The IQ Analyzer displays the most comprehensive list of
metered parameters in its class. Multiple parameters,
such as currents of phases A, B and C, are displayed
simultaneously for more thorough real-time monitoring.
Custom screens can be configured to view a parameter
grouping, such as volts, amperes and power factor, for
convenience, or to concurrently observe their
relationships as conditions change.
1-2.2 HARMONIC DISTORTION ANALYSIS
Current and voltage distortion data are displayed by the
IQ Analyzer and/or accessible through the
communications port. This includes:
• % THD
• K-Factor
• Crest Factor
• CBEMA Factor
• Harmonic magnitudes through the 50th
• Harmonic phase angles through the 50th
A snapshot sample of this information may be activated
by user commands, discrete inputs, programmable
thresholds, or minimum/maximum updates to capture
distortion data during conditions of interest. To help
eliminate nuisance alarms, harmonic distortion
information can be captured and relay outputs activated
when THD exceeds a:
• Programmable percentage of fundamental
or
• Programmable magnitude, such as amperes,
threshold
1-2.3 EXTENSIVE I/O AND COMMUNICATIONS
CAPABILITIES
One analog and three digital inputs are provided to
interface with sensors and transducers. Three analog
output and four relay contacts are furnished to share
data with PLCs and control systems, and to actuate
alarms and control relays. Terminals are captive clamp
type and finger safe (Figure 2-2). With the
communications option, IQ Analyzer can be remotely
monitored, controlled and programmed.
1-2.4 DISTURBANCE INFORMATION
The 6200 Series Analyzer or with the communications
option and IMPACC Series III and Wave Form Display
software, a waveform analysis will construct waveforms
of up to 56 cycles of all currents and voltages, including
neutral and ground, to help troubleshoot undervoltage/
sag and overvoltage/swell conditions. For example, by
programming a reset threshold, the duration of the
voltage disturbance can also be indicated.
1-2.5 HIGH ACCURACY
Advanced electronic circuitry enables IQ Analyzer to
comply with the ridged ANSI C12.16 Class 10 accuracy
standard for revenue meters. In addition, accuracy is
maintained in applications with high distortion levels.
This includes systems exhibiting a 3.0 Crest Factor,
harmonics up to the 50th multiple of the fundamental,
and frequency variations.
1-2.6 OPERATIONAL SIMPLICITY
The IQ Analyzer’s “Meter Menu” makes commonly
viewed parameters easy to access and understand. For
additional information, the “Analysis” screens provide
comprehensive data on harmonic distortion, current/
power demands, trending and event/alarms. IQ
Analyzer also has a “Help” pushbutton to assist in
programming, troubleshooting and operating the device.
This manual is accurate to firmware version 1.16.
