Usually power is generated and distributed in three phase system, and therefore it is obvious that we would need three phase transformers ...

  An auto transformer is an electrical transformer having only one winding. The winding has at least three terminals which is explained...

Sumpner's test or back to back test on transformer is another method for determining transformer efficiency , voltage regulation and h...

These two transformer tests are performed to find the parameters of equivalent circuit of transformer and losses of the transformer . Open ...

In a practical transformer - (a) Some leakage flux is present at both primary and secondary sides. This leakage gives rise to leakage re...

Losses in transformer In any electrical machine , 'loss' can be defined as the difference between input power and output power. A...

Magnetic leakage In a transformer it is observed that, all the flux linked with primary winding does not get linked with secondary wi...
