Short-circuit test : ウィキペディア英語版 | Short-circuit test The purpose of a short-circuit test is to determine the series branch parameters of the equivalent circuit of a real transformer. ==Method== The test is conducted on the high-voltage (HV) side of the transformer where the low-voltage (LV) side or the secondary is short circuited. The supply voltage required to circulate rated current through the transformer is usually very small and is of the order of a few percent of the nominal voltage and this 5% voltage is applied across primary. The core losses are very small because applied voltage is only a few percentage of the nominal voltage and hence can be neglected. Thus the wattmeter reading measures only the full load copper loss.
