Metering Devices
Power Xpert Meter 4000/6000/8000, continued
Notes
These specifications are subject to change without notice and represent the maximum capabilities of the product with all options installed. This is not a complete feature list. Features and functionality
may vary depending on selected options, firmware version and product model. Please refer to the technical data sheet and User Manual for detailed specifications.

When used with third-party device and I/O option.
Power Xpert Meter
Feature 4000 6000 8000 Benefit
Communications and I/O, continued)
Trend measurements CSV file export
■■■
Easily export trend measurements to third-party applications, e.g., Microsoft Excel in
standard CSV file format
I/O (8 digital inputs, 3 relay outputs, 2 solid-state KYZ outputs)
■■■
The Power Xpert I/O Card is extremely flexible and can be used in a large variety of
different applications. Digital inputs and relay outputs can be programmed to interact
during various conditions defined by the user. Various third-party devices, such as
alarm, pulse meters, trip units, sensors can be easily integrated to the Power Xpert
Meter. Triggers and events can be tied to the meters standard functions such as e-mail,
logs and trends
Time Synchronization
NTP time synchronization up to 1 millisecond accuracy
■■■
Network Time Protocol support enables the meter to synchronize time over the network up
to the 1 millisecond resolution
GPS time synchronization up to 1 millisecond accuracy
■

The GPS option allows the meter to synchronize time over the GPS satellite positioning
system up to the 1 millisecond resolution
Logs
Trend logging
■■■
Log trend information for easy statistical analysis
Load profile
■■■
Review the load profile graph to get a better understanding of your electrical load
versus time
Event logging
■■■
Log events for retrospective event analysis
Memory and Storage
Standard memory, GB 248Store large amounts of waveform captures and events for historical analysis
Harmonics
Harmonic levels 127 127 127 Provides extremely fast, high resolution D/A conversion
Total harmonic distortion (THD)
■■■
Review the total harmonic distortion level directly on the meter
Delta-Sigma D/A conversion technology
■■■
Provides extremely fast, high resolution D/A conversion
Harmonics over-sampling (4096 samples per cycle)
■■■
Over-sampling enables the usage of Anti-Aliasing technology, increasing accuracy
Anti-alias filtering
■■■
Technology to remove out-of-band signal components resulting in more accurate data
Individual harmonics
■
■■
Review individual harmonic levels directly on the meter
Total demand distortion (TDD)
■
■■
Identify harmful harmonics in e.g. lightly loaded variable-speed drive environments where
THD may be high but not relative
Interharmonics
■ ■ Interharmonics allow you to see what is going on between the integer multiples of the
fundamental. Zoom in on the harmonics trend graph and review frequency content every
5 Hz instead of every 60 Hz
Highlights
Sub-cycle disturbance capturing
■■■
Capture fast voltage changes/low frequency transient (e.g. capacitor switching transient)
dV/dt triggers for sub-cycle oscillatory transients
■■■
Detect and record a large magnitude oscillation transient resulting in equipment damage
Absolute threshold and dV/dt triggering
■■■
Detect and record if a surge suppressor is necessary
Power quality index—standard (includes dv/dt count, %TDDi and %THDv)
■
■■
Complex power quality data put into simple graphic format
Power quality index—enhanced (includes Standard Index plus Sag level,
Swell level and Flicker)
■ ■ Complex power quality data put into simple graphic format (includes ITIC events
and flicker calculations)
Flicker calculations
■■
Detect and quantify low frequency rms voltage variations causing incandescent
lighting flicker
Automatic trigger setting
■■
Trigger thresholds are automatically set according to ITIC (CBEMA) standard, no need to
figure this out by yourself
Automatic event severity analysis
■■
Automatically analyze the severity of the event with the ITIC (CBEMA) performance curve
plot, see where the event actually hit
