... thermal modelling of power transformers. No-load losses are made up of hysteresis and eddy loss in the transformer core, and these losses are present whenever the transformer is energized. Hysteresis loss is due to the elementary magnets in the material aligning with the alternating magnetic field. ...

Basics of Control Components
... A typical control circuit includes a control load and one or more components that determine when the control load will be energized. Some control loads, such as relays and contactors, activate other devices, but other control loads, such as indicator lights, do not. For example, the following illust ...
