A 150-kVA, 7200-600-V, 60Hz, single phase transformer operating at rated conditions has an hysteresis loss of 527 W, an eddy current loss of 373 W, and a conductor loss of 2000W. The transformer is to be used on a 50 Hz system, with the restriction that it maintain the same maximum core flux and the same total losses. Determine (a) the new voltage rating; (b)the new kVA rating.
