Question. Transcribed Image Text: ... Iron loss in a transformer: a) is dependent on load current. Ob) is a function of the resistance ... WebCore losses occur in the steel core of the transformer due to the magnetizing current needed to energize the core. The magnetizing current remains the same during no-load and full load. Core losses are also known as iron losses in transformers. The core losses constitute two components: Hysteresis losses and eddy current losses.

WebFeb 4, 2024 · In a three-phase transformer, we can classify the losses in the different parts as follows: Core losses occur in the ferromagnetic core of the transformer. Core loss is commonly termed iron loss, as distinguished from copper loss, the loss in the coil windings. Most of the time, core losses are governed by hysteresis; that is, the lag of ...

WebApr 10, 2024 · Therefore to reduce the iron losses in a transformer, the core should be made of a material having high permeability and high resistivity since high permeability helps in carrying high magnetic flux and high resistivity helps out by preventing eddy currents by providing low conductivity.
