Winding Resistance Measurement Test of a Power Transformer

by

In the winding resistance measurement test of a power transformer, we simply use either the ammeter-voltmeter method or the Kelvin Double Bridge method. Actually, we inject DC current to the winding of the transformer. Additionally, we measure the voltage drop across it. Then we determine the resistance value of the winding by dividing the voltage … Read more
