3 Phase Transformer Winding Resistance Meter , ISO9001 20A DC Resistance Tester

Three-phase Transformer Winding Ohmmeter

Model: TWO320

Three-phase Transformer Winding Ohmmeter is designed to accurately measure three-winding resistance of power transformers. It can save time by testing three-winding without having to disconnect and reconnect leads. The test sequence can be selected as three-winding measurement of HV or LV separately, or single winding test.

Main Features

1) DC test current up to 20 A maximum

2) Automated three-winding measurement capability

3) Fast testing with one-time connection principle

4) Calculates three-phase resistance unbalance rate automatically

5) Fast auto safety discharge circuit

6) Able to print the test results directly via built-in printer
