Description
The PowerPad portable power monitor is a three-phase power quality analyzer
that is compact and shock-resistant. It is intended for technicians and engineers
to measure and carry out diagnostic work on one, two, or three phase low voltage
networks.
You are able to obtain instant waveforms of an electrical network’s principal
characteristics, and also monitor their variation over a period of time. The multi-
tasking measurement system simultaneously handles all the measurement
functions of the various magnitudes, detection, continuous recordings, and their
display without any constraints.
The PowerPad unit has these features.
• Measurement of RMS voltages up to 480V (phase-to-neutral) or 830V
(phase-to-phase) for two, three, or four-wire systems
• Measurement of RMS currents up to 6500 Arm
• Frequency measurement (40…70 Hz systems)
• Calculation of neutral current for WYE configurations
• Calculation of Crest Factors for current and voltage
• Calculation of the K Factor for transformers
• Calculation of short-term flicker for voltage
• Calculation of the phase unbalance for voltage and current (three-phase
systems only)
• Measurement of harmonic angles and rates (referenced to the fundamental
or RMS value) for voltage, current, or power, up to 50th harmonic
• Calculation of overall harmonic distortion factors
• Monitoring of the average value of any parameter, calculated over a period
running from 5 seconds to 2 hours
• Measurement of active, reactive, and apparent power per phase and their
respective sum total
• Calculation of the power factor, displacement power factor, and tangent
factor
• Total power from a point in time, chosen by the operator
• Recording, time stamping, and characterization of disturbance (swells,
sags, and interruptions, exceeding power and harmonic thresholds)
• Detection of transients and recording of associated waveforms
