The AEMC 8320 PowerPad® Jr. is a portable, single-phase power quality analyzer designed for technicians and engineers. It features a compact, shock-resistant design and is suitable for measuring and diagnosing power quality issues on single or three-phase balanced load networks. The device can measure voltages up to 660 V RMS or DC, and currents up to 6500 A AC or 1400 A DC depending on the probe. It displays various parameters including minimum, maximum, and average voltage and current, crest factor, peak values, and K-Factor. It calculates and shows active power (Watts), reactive power (VARs), apparent power (VA), power factor, and displacement power factor for single-phase and balanced three-phase systems. The analyzer provides total harmonic distortion (THD-F and THD-R) for voltage and current and displays individual harmonic values up to the 50th harmonic. It captures, displays, and stores inrush current waveforms and statistics, and can save up to eight screen captures and 1MB of trend data. Configuration is possible via DataView® software or the device's front panel, and data can be downloaded through an isolated USB port. It can record up to 4096 alarm events based on ten different thresholds and monitors up to 17 power quality parameters. Typical applications include energy metering (kWh, kVAh, VARh), motor startup analysis, power distribution verification, and troubleshooting of power systems and machinery to identify harmonic issues.
