Can We Operate a 60Hz Transformer on 50Hz Supply & Vice Versa? may use an additional current limiter device (Inductor or resistor) in series with the primary winding of a transformer by which we can increase the overall impedance to reduce the extra current. This way, we can use a 60Hz transformer on 50Hz AC Supply.[email protected]

Current Transformer : Construction, Working, Types and Its ... Transformer Device Working Principle. The working principle of the current transformer is somewhat different when we compare it with a normal voltage transformer. Similar to the voltage transformer, it includes two windings. Whenever AC supplies throughout the primary winding, then alternating magnetic flux can be generated, then AC will be induced within the secondary winding.
