Why does open-circuit test give core loss/short-circuit test give copper loss?

2019-06-26

Iron core losses: The magnetic flux in the transformer is flowing on the iron core, and the iron core has magnetoresistance to the magnetic flux, which will generate heat so that this is why open-circuit test gives iron core losses; Copper losses: Coil
