Umda wokhuseleko lwerhasi ye-transformer ubandakanya:

1) I-multi-phase short circuit ngaphakathi kwe-transformer.

2) I-Short-circuit, i-winding kunye ne-iron core okanye i-shell yesekethe emfutshane ye-transformer

3) Ukungaphumeleli kwentsimbi kwi-transformer.

4) Ngaphantsi kweoli yeoli okanye ukuvuza kweoli ye-transformer.

I-5) Uqhagamshelwano olubi phakathi kokudibanisa ukudibanisa okanye ukuthungwa kweengcingo akuqini.
