How is the power loss in a transformer calculated? Connections to the transformer primary windings are at the top of overhead and underground transformers, and the left panel of padmount transformers. The power loss in a transformer winding can be calculated by using the current in the winding and its resistance, in formula for power, p = i 2r.

This formula is the reason copper losses are sometimes called i 2r losses.

To minimise the losses the resistance of the winding must be kept low, using wire Temperature limits • oil temperature = 100/105oc • average winding temperature( paper)= 85oc for normal paper & 95 oc for thermally upgraded paper & 125 or 145 c for nomex • hotspot winding temperature (paper) based on daily average ambient=95oc for normal paper & 110oc for thermally upgraded paper This formula is the reason copper losses are sometimes called i 2r losses. Where can i find the practical transformer handbook?
