ue (frequency being unchanged), the coreflux will be increased according to equation (34) and the core losseswill be increased according to equations (35) and (36). If, on the other hand, a transformer is used with a frequencyless than the rated frequency (the voltage applied to the primarybeing… … ALTERNATING-CURRENT MACHINERY 269 The increase of core loss due to increase of primary appliedvoltage, or to decrease of frequency, or to both, may be compen-sated for by reducing the allowable current output, and therebyreducing the copper loss, in order that the total heating of the trans-former…
