All those transformer losses which are always constant, regardless of the load variations, are known as No-load losses. They do not vary according to the loading on a transformer. Even a small reduction in no-load losses can lead to significant energy savings in large transformers. Core losses...
Accordingly, methods used to separate the no-load losses into its constituent parts are also reviewed. Comments regardings the application of loss separation to transformer cores, as opposed to Epstein samples, are included to serve as a basis for future investigations. 展开 ...

No-Load Transformer Theory: On no-load, the transformer experiences core losses but no copper loss or leakage reactance, with current components for magnetizing and core losses. Magnetizing and Core Loss Currents: The no-load current consists of a magnetizing component (reactive) and a core loss...
