Product Description

Zinc Oxide Arrester Live Tester

Darui Electric recommends

Performance Features:

1. It can measure resistive current either by direct test 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. Reference voltage signal can use 3PT, 1PT, no PT, wireless, induction, etc.

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

5. To facilitate analysis of resistive current, side-phase compensation can be either prohibited or allowed.

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