Product Description

General introduction

GDZRS series Winding DC resistance tester is optimal designed for measuring three phase winding DC resistance of big capacity transformer. It can test three phase winding DC resistances at the same time.


Features

1. For on-load variable transformer, no need to discharge, just adjust tap switch directly.
2. The measurement time is 1/3 of tradition single phase measurement, that working time and labor intensity is shorten.
3. Big screen LCD display, clear and visual, easy operation.
4. Built-in panel printer and big capacity memory, easy to get printing result and convenient to storage data.
5. Stable data, fast testing and good repeatability, suitable for transformer DC resistance on-site measurement.
