Why Transformer does not work on DC supply?

WebAnswer: A DC test on a transformer is a test that is performed to determine the insulation resistance of the transformer windings. This test involves applying a direct current (DC) voltage to the transformer windings and measuring the resulting current. The insulation resistance is calculated by ... WebFeb 23, 2024 · Yes, any DC current into the transformer can cause the core to saturate. It's the average value of the waveform that determines its DC content. Thus a unipolar signal has an average DC value, so cann0t be applied to a transformer. To block any DC, you can use a large series capacitor which will pass the AC but not the DC.
