10.1 A 3 MVA, 50 Hz, 11 kV, 3-phase, star-connected Alternator when supplying 100 A at zero pf leading has a line to line voltage of 12.37 kV. When the load is removed the terminal voltage falls down to 11 kV. Determine the voltage regulation of the Alternator when supplying full load at 0.8 pf lagging. Assume an effective resistance per phase of 0.4
