The PROVA23 Power Harmonic and Leakage Clamp Meter is a powerful tool for electrical testing, equipped with a variety of practical functions. It can measure the true RMS values of current and voltage, ensuring accurate and reliable results. The leakage current resolution is as low as 10μA, allowing for precise detection of minor leakage currents. The device offers harmonic analysis of current and voltage up to the 99th order, providing a comprehensive understanding of high-frequency harmonics with a frequency range reaching up to 5/6 KHz. Additionally, it features a fast peak lock function, with a sampling time of 39µs for 50Hz and 33µs for 60Hz, to capture instantaneous peak values.

In terms of power system analysis, the PROVA23 can measure active power (W, KW, HP), reactive power (VAR, KVAR), apparent power (VA, KVA), as well as power factor (PF) and phase angle (Φ). It also analyzes total harmonic distortion (%THD-F) and crest factor (C.F.). The device supports the measurement of balanced three-phase power and the phase sequence of three-phase power supplies, and it allows users to set the CT ratio from 1 to 250. It also features maximum, minimum, and hold functions, facilitating data recording and analysis for users. The AC current measurement range is from 0.5 to 100A, and the AC voltage measurement range is from 5V to 600V. When not in use, the device has an auto-shutoff function after 30 minutes to save power, which can be disabled according to user requirements.

The PROVA23 Power Harmonic and Leakage Clamp Meter uses a clamp-on method, allowing for online harmonic analysis without affecting normal operations. It is widely used in power system maintenance, industrial equipment inspection, and electronic device development. It helps professionals quickly and accurately diagnose problems in power systems, ensuring their stable operation.
