DC Resistance Meter-YR-20W
DC Resistance Meter-YR-20W
Product Code : YR-20W
Product Description
Introduction

YR-20W type DC resistance meter is applicable to measure the DC resistance of power and distribution transformers, current transformers up to 35kV. It can also be used during temperature rise test. It is especially designed for the transformers whose resistances of HV winding and LV windings have a big difference.

Features

  • Interval time of 10s,30s and 60s for selection during temperature rise test;
  • Double power with constant current;
  • Color touch panel with easy operation;
  • Test the LV winding, HV winding at the same time or seperately;
  • With temperature rise software to handle the test data;
  • USB port to download the test data to USD flash disk for the temperature rise curve;
  • 485 communication port to communicate with the computer;
  • Protection if the tester is connected with 380V AC power supply;
  • Discharge alarming;
