Electrical Machines Short circuit test is performed on a transformer with a certain impressed voltage at rated frequency. If the short circuit test is now performed with the same magnitude of impressed voltage, but at frequency higher than the rated frequency then The magnitude of circuit as well as the power factor will decrease. The magnitude will both increase. The magnetude of current will increase, but power factor will decrease. The magnitude of current will decrease but the power factor will increase. The magnitude of circuit as well as the power factor will decrease. The magnitude will both increase. The magnetude of current will increase, but power factor will decrease. The magnitude of current will decrease but the power factor will increase. ANSWER DOWNLOAD EXAMIANS APP
