G-type Wired Handheld Zinc Oxide Arrester Live Tester



G-type Wired Handheld Zinc Oxide Arrester Live Tester



I. Instrument Features




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

  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 via 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, both disabling and enabling side-phase compensation are allowed.

  6. To save printing paper, both allowing and prohibiting waveform printing are supported.
