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
