We have a transformer designed to operate at 60 Hz. The voltage ratings are 4800 V rms and 240 V rms for the primary and secondary windings, respectively. The transformer is rated for 10 kVA. Now, we want to use this transformer at 120 Hz. Discuss the factors that must be considered in setting ratings appropriate for operation at the new frequency. (Keep in mind that for best utilization of the material in the transformer, we want the peak flux density to be nearly at saturation for both frequencies.)
