which part of transformer heats up the most and why? windings,
core or oil .
Answer Posted / engr. shomaz ul haq
Series losses (i.e. copper/resistive and leakage flux losses) in the primary and secondary windings of a transformer whereas the parallel losses (excitation branch losses) can be ignored as very little current travels through it thus heating in less amount as compared to series losses.
