The results of open-circuit and short-circuit tests on asingle-phase, 25kVA 440V / 220V, 60Hz transformer are as follows:
Open-circuit test (primary open-circuited, withinstrumentation on the secondary side): 220V, 9.6A, 710W.
Short-circuit test (secondary short circuited, withinstrumentation on the primary side): 42V, 57A, 1030W.
Determine the values of Req, Xeq, Rc and Xm (in per-unit) at the transformer base kVA rating.
