noun (Electrical engineering: Circuits, Electrical power, Computing and control) Losses are energy and capacity lost in the operation of an electric system. ⇒ By using transformers, the voltage of the power can be stepped up to a high voltage so that the power may be distributed over long distances at low currents and hence low losses. ⇒ Losses occur principally as energy transformations from kilowatt hours to waste heat in electrical conductors and apparatus. ⇒ Losses are energy and capacity lost in the operation of an electric system.
