AC MACHINES-1 (66761) Theory
Completion requirements
4. Understand equivalent circuit of transformer, magnetic leakage and leakage reactance of transformer.
4.6. List the disadvantages of magnetic leakage.
As leakage flux increases, efficiency of the transformer decreases as a portion of the leakage flux may induce eddy currents within nearby conductive object such as the transformers support structure, and be converted to heat. When represented as inductance, it only represents reactive power loss
