area of evaluation is outside of the range of
acceptable values.
Schneider Electric – Square D PowerLogic PM800 series power meter
26
Standard Waveform Capture (PM850)
● Waveform Capture
● Manual or Alarm initiation
● 128 samples/cycle, 3 cycles
● Waveforms give a graphical
representation of what’s happening
with your power during a particular
moment.
● Quickly isolate potential power
problems.
● Excellent for troubleshooting
problems that occur continuously.
Schneider Electric – Square D PowerLogic PM800 series power meter
27
Disturbance Detection and
Advanced Waveform Capture (PM870)
● The PM870 has the ability to detect, alarm upon, and capture voltage
and current sags and swells that can cause unwanted trips and process
interruptions, damage motors and more.
● Twelve factory configured voltage disturbance (sag/swell) alarms
provide warning and trigger a disturbance waveform capture.
● Disturbance alarms can be reconfigured for current sag and current
swell using System Manager software.
Voltage sags are often
caused by heavy loads
being started. The
PM870’s disturbance
detection features can
help isolate the source
of troublesome sags
and swells.
Schneider Electric – Square D PowerLogic PM800 series power meter
28
Disturbance Detection and Advanced
Waveform Capture (continued)
● Advanced waveform capture (PM870)
provides a detailed picture of the
disturbance event
● Configurable from 185 cycles on one
channel at 16 samples/cycle up to 3
cycles on six channels at 128
samples/cycle
Poor power quality can lead to
costly downtime. A PM870’s
disturbance waveform capture
can provide the information
needed to diagnose an event.
