DIEGO, Calif. – December 8, 2009
AEMC 3945 PowerPad
and records the waveforms, harmonics and transients produced by an electrical system. For troubleshooting
purposes, this instrument displays volts, amps and harmonic content in real time and takes pictures to document
and analyze. The full color display allows one to view and analyze each signal clearly and easily. Its high speed
sample rate, at 256 samples per cycle, provides excellent reliability in reproducing waveforms and capturing
transients that happen as fast as 62.5 µs.
PowerPad's 4MB of memory is conveniently partitioned to store four different types of data, synchronized or
independent of each other. Store up to 12 screen snapshots, up to 50 captured transients that contain four cycles
for each active input and 4096 alarm events. Trend data can also be recorded for days, weeks or even months.
Six direct access function buttons quickly allow one to view: waveforms, harmonics, transients, alarms, record and
power & energy. Waveforms display volts, amps, THD and crest factor by phase or for all phases. Display harmonics
out to the 50th for volts, amps and VA. Set, capture and display transients by selecting the threshold and number
of transients to capture; PowerPad then captures the waveforms for each transient. As many as 1200 waveforms can
be captured. Configure, capture and display up to 4096 alarm events based on up to ten different trigger
variables. Set up and record trend data at selectable rates from one sample/second to one sample every 15 minutes
on as many as 22 different variables for all phases. Finally, display watts, VARs and VA by phase and total.
Accumulate totals and see whether the energy is inductive or capacitive.
This three-phase power quality analyzer can be used for the following applications: verification of power
distribution circuits, measurement and recording of power system quality (kW, VA, VAR), energy metering (kVah,
VARh, kWh), determines harmonic problems originating from source or load, in plant troubleshooting of power
distribution panels and individual machinery, and much more.
