چکیده:

Harmonic currents, generated by non-linear loads, increase the losses and temperature inside the power transformer. The winding hot spot temperature is one of the mostcritical parameters that affect the useful life of the power transformers. This paper deals with the transformer field solution and the determination of field distribution on thecomponents of transformer. In addition the hot spot and top oil temperature will be determined. Last percentage of loss of transformer life time under harmonic condition will be analyzed.
