Product Description

YR-20W type DC Resistance Meter

Introduction

YR-20W type DC resistance meter is applicable to measure the DCresistance of power and distribution transformers, current transformers upto35kV. It can also be used during temperature rise test. It is especiallydesigned for the transformers whose resistances of HV winding and LV windingshave a big difference.

Features

Interval time of 10s,30s and 60s for selection during temperature risetest;
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 thetemperature rise curve;
485 communication port to communicate with the computer;
Protection if the tester is connected with 380V AC power supply;
Discharge alarming;
