Q. A60-Hz, 100-kVA, 2400/240-V(rms) transformer is used as a step-down transformer from a transmission line to a distribution system. Consider the transformer to be ideal.
(a) Find the turns ratio.
(b) What secondary load resistance will cause the transformer to be fully loaded at rated voltage (i.e., delivering the rated kVA), and what is
the corresponding primary current?
(c) Determine the value of the load resistance referred to the primary side of the transformer.
