Four common energy losses in a transformer are:
Core Losses (Hysteresis and Eddy Current Losses): These occur in the transformer core due to the alternating magnetic flux, causing energy dissipation through heat.
Copper Losses: These losses arise from the resistance in the windings of the transformer, where current flow generates heat.
Leakage Flux Losses: Incomplete magnetic flux linkage between the primary and secondary windings leads to energy loss.
Dielectric Losses: Energy is lost due to the imperfect insulation material in the transformer.
