Power Loss

The power loss of a transformer consists of iron losses (caused by induction and mains frequency) and copper losses (caused by the current through the winding and its temperature). Iron losses are no-load losses and are therefore always present. They can be optimized by the design and type of core laminations. Copper losses are load-dependent, they are always specified at nominal load or nominal current and can be influenced by the quality of the winding and the amount of copper weight.
