GDZC-20S Three Channel 20A Transformer Winding Resistance Tester
The three-phase measurement applies to the windings of YN star connection with neutral lead. For the windings of yn connection, since difference exists between the three-phase and single-phase measurement results due to the effect of copper bus connected, single-phase measurement is recommended.
