No-load loss
No-load 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. No-load loss typically depends on the operating voltage of a grid unit and can be attributed to:
- dielectric loss in cables;
- core loss in electric transformers;
- some types of losses in synchronous condensers ;
- loss in the electromechanical measuring devices ;
- corona loss in high-voltage lines.
