Description
The PROVA-6605 Power & Harmonics Tester is a high-precision instrument designed for comprehensive AC power measurement and harmonic analysis. It supports single-phase and three-phase systems, measuring active (W, KW, HP), reactive (VAR, KVAR), and apparent power (VA, KVA), as well as energy (WH, KWH), power factor, and phase angle.
With True RMS measurement and fast peak detection (39 μs for 50 Hz, 33 μs for 60 Hz), it accurately captures voltage and current even under non-linear load conditions. The device performs non-interrupted harmonic analysis from 1st to 99th order, with a basic accuracy of 2% for harmonics. It calculates total harmonic distortion (%THD-F) and monitors the crest factor (CF) for both voltage and current.
The PROVA-6605 includes resistance and continuity testing with audible alerts, supports 1 to 250 programmable CT ratios, and provides functions for Max, Min, and Data Hold. It is portable, battery-operated, and features a 30-minute auto power-off, making it ideal for field and laboratory use.
