Product Details

Zinc Oxide Arrester Live Tester



Darui Electric recommends for you



Performance Features:

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

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 use 3PT, 1PT, no PT, wireless, or induction methods.

4. The instrument is equipped with rechargeable battery, calendar clock, and micro printer, and can store 500 sets of measurement data.

5. For the convenience of analyzing resistive current, side-phase compensation can be either prohibited or allowed.

6. To save printing paper, waveform printing can be disabled.
