Product Features; Description - AEMC 8335 Power Pad User Manual

2.1 Description

The easy-to-use, compact and shock-resistant PowerPad
phase power quality analyzer equipped with four current probes and five voltage
inputs. It is intended for technicians and engineers to measure and carry out
diagnostic work and power quality work on one, two or three phase low voltage
networks.
The PowerPad's 2GB of memory is conveniently partitioned to let you store four
different types of data, synchronized or independent of each other. You can store
up to 50 screen snapshots, up to 210 captured transients that contain four cycles
for each active input, and 10,000 alarm events from up to 40 different parameters.
You can also record trend data for days, weeks or even months.
Six access buttons quickly display the following functions. Note that these func-
tions can be accessed during a recording.
Waveforms – Display Volts, Amps, THD and Crest Factor by phase or for all
phases. You can display all the voltage inputs on one screen, phase-to-phase
or phase-to-neutral. Real-time phasor diagrams can be displayed for volts and
amps, also by phase or for all phases including phase unbalance.
Harmonics – Display Harmonics out to the 50th for Volts, Amps and VA.
Individual Harmonics are displayed as a percentage and value for Volts, Amps
and VA. Harmonic direction and sequencing can also be displayed.
Transients or Inrush Current – Set, capture and display transients. You select
the threshold and the number of transients to capture. The PowerPad
tures four waveforms for each transient; the triggering waveform as well as one
pre-triggered and two post-triggered waveforms. As many as 210 transients each
consisting of 4 waveforms per channel for up to 8 channels can be captured.
Trend Recording – Record and display trend data at user selectable sample
rates from 1/sec to 1/15 minutes and user programmable recording periods into
2GB of memory.
Recordings can only be downloaded through the USB port. Extremely long
recordings will take a long time to download (> 2H per 100MB). Also,
keep in mind that Microsoft
sheet and Access has limitations as well.
