No-load loss
From Wikipedia, the free encyclopedia
No-load loss (also called "fixed loss") is a portion of the loss of electricity that does not depend on the power being distributed through an electric circuit, as opposed to the load loss.[1] No-load loss typically depends on the operating voltage of a grid unit[2] and can be attributed to:
- dielectric loss in cables;[3]
- core loss in electric transformers;[4]
- some types of losses in synchronous condensers (rotor surface losses, pulsating losses in stator teeth, and losses in the stator due to higher harmonics of the rotor field);[5]
- loss in the electromechanical measuring devices (low, e. g. an "analog" electrical meter consumes less than 1.5 Watts of power);[6]
- corona loss in high-voltage lines.[7]
