Question:

The following readings are taken from the results of an open- and a short-circuit test on an 800-MVA, three-phase, Y-connected, 26-kV, two-pole, 60-Hz turbine generator driven at synchronous speed: The number in parentheses are extrapolations based upon the measured data. Find

(a) The short-circuit ratio,

(b) The unsaturated value of the synchronous reactance in ohms per phase and per unit, and
