Transformer Winding Resistance Testing
Winding Resistance Test DefinitionThe winding resistance test of a transformer checks the health of transformer windings and connections by measuring resistance.Purpose of Winding Resistance TestThis test helps in calculating I2R losses, winding temperature, and identifying potential damage or abnormalities.Measurement MethodsFor star connected winding, the resistance shall be measured between the line and neutral terminal.For star connected autotransformers the resistance of the HV side is meas
