something lost, especially money lost at gambling. Inverse of winnings.
The general term applied to energy (kWh) and capacity (kW) lost in the operation of an electric system. Losses occur principally as energy transformations from kWh to waste-heat in electrical conductors and apparatus. This waste-heat in electrical conductors and apparatus. This power expended without accomplishing useful work occurs primarily on the transmission and distribution system.
Power that is harvested by a wind generator but is not transferred to a usable form. Losses can be from friction, electrical resistance, or other causes.
Electric energy or capacity that is wasted in the normal operation of a power system. Some kilowatthours are lost in the form of waste heat in electrical apparatus such as substation conductors. Line losses are kilowatts or kilowatthours lost in transmission and distribution lines under certain conditions.
All current carrying conductors have a non-zero resistance (unless they happen to be superconducting!). As a result, current in a conductor produces a voltage drop -- along the conductor -- which results in less power being delivered to the load. This voltage drop, called the ohmic or IR drop, is the product of the current and the resistance of the wire carrying the current. NEC and other electricians' guides have tables for the resistance per foot of common copper and aluminum wire gauges. For example, #10 AWG copper wire (specifically 7-strand USE #10 AWG at 75 deg C) has a resistivity of 1.29 ohms per thousand feet.. A 100 foot length of USE 10 carrying 5A from a 24 volt source will suffer a 0.65V drop, yielding 23.35V at the load end of the wire. This represents a 2.7% voltage (and power) reduction at the load. 3% is the maximum voltage drop representing good design practice, with many installers designing to 1% or less.
A motor converts electrical energy into a mechanical energy and in so doing, encounters losses. These losses are all the energy that is put into a motor and not transformed to usable power but are converted into heat causing the temperature of the windings and other motor parts to rise.

As electricity travels through the national grid, a proportion of energy is lost as heat due to the resistance in the lines. The greater the distance the electricity travels and the lower the voltage of the line, the higher the losses are.
A general term applied to the energy that is converted to a form that can not be effectively used (lost) during the operation of an energy producing, conducting, or consuming system.
