When the transformer is on load, the secondary winding is connected with load as in figure (1) and current I2 is flowing through load. Operation of Transformer On load Figure (1) shows a transformer with a load connected across the secondary winding. The load current I2 flowing through the secondary turns sets up its own […]

Shaded pole induction motor is more or less similar to single-phase induction motor. The stator poles of this motor are wound only with main winding, so as to make them electromagnets. The pole has a slot cut at one third for one end for housing high reactance but low resistance copper bars enclosing a part

The Open Circuit and Short Circuit Test on Transformer can be used to determine the efficiency and regulation of a transformer at any predetermined load for that we do not have to actually load the transformer. The parameters of the equivalent circuit of a transformer can be obtained by using the open circuit (O.C.) test
