What is no-load loss？
No - load loss, also known as iron loss or no - load iron loss, refers to the electrical energy consumed by a transformer in a no - load state (that is, the secondary winding is open - circuited and there is no load current). This part of the loss mainly occurs in the iron core of the transformer and is an inevitable part of energy loss during the operation of the transformer. Understanding no - load loss is of great significance for evaluating the efficiency of a transformer and selecting an appropriate one. The following is a detailed explanation of no - load loss:
1. Definition
No - load loss refers to the loss generated in the iron core when the transformer is in a no - load state, that is, when the secondary winding is open - circuited, and the primary winding is still connected to the power supply. These losses mainly consist of the following two parts:
Hysteresis loss: The loss caused by the hysteresis effect of the iron core material.
Eddy - current loss: The loss caused by eddy currents in the iron core.
