Model G Wired Handheld Zinc Oxide Arrester Live Tester



I. Instrument Features




  1. It can measure resistive current either by direct testing method or by third harmonic indirect testing method.

  2. Three-phase voltage and three-phase current are collected and displayed simultaneously, achieving true three-phase simultaneous measurement.

  3. The reference voltage signal can be obtained through 3PT, 1PT, no PT, or induction methods.

  4. The instrument is equipped with a rechargeable battery, calendar clock, and micro printer, and can store 256 sets of measurement data.

  5. For convenient analysis of resistive current, side-phase compensation can be either disabled or enabled.

  6. To save printing paper, waveform printing can be either allowed or prohibited.
