Answer :

Transformer electrical characteristics:

Area of primary and secondary conductors, Apri and Asec:

Winding loss Pw:

Flux density and core loss:

Leakage inductance:

Rated power:

Load losses:

Rated voltage:



Short circuit current:

No load current:

Effect of a rise in temperature on transformer:

High-efficiency transformer has a low rise in temperature while low-efficiency transformer has high rise in temperature. Temperature rise affects the transformer span. The rise in temperature may breakdown insulation which may cause failure of the transformer.
