Product Description

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)Adopt 4-wire method for resistance measurement

2)DC test current up to 100 A maximum
3)User-selectable maximum current range
4)Resistance measurement from 1mΩ to 100kΩ
5)Fast auto safety discharge circuit
6)Able to download test results via USB interface
7)Able to print the test results directly via built-in printer
