PowerPad Model 8335

DESCRIPTION

The PowerPad

Model 8335 is a three-phase power quality analyzer that is easy-to-use,

compact and shock-resistant. 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 300 captured transients that contain four cycles for each active input, and
10000 alarm events from up to 40 different parameters. You can also record trend data for
days, weeks or even months.

Six direct access function buttons quickly let you see:

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 – Set, capture and display transients. You select the threshold and the number of
transients to capture. The PowerPad

then captures four waveforms for each transient; the

triggering waveform as well as one pre-triggered and two post-triggered waveforms. As many
as 300 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
