Question

The OCC of a 3 phase , 50 Hz synchronous machine is given by the following data; Field current (Amp) 40 80 100 120 140 170 240 Voc (line) 1000 1900 2200 2450 2600 2750 3000 Under short circuit condition a field current of 40 A gives the full load stator current. The armature resistance and leakage reactance per phase are known to be 0.01 and 0.12 pu. When the machine is operating as motor drawing full load current at the rated terminal voltage of 3.3 kV and 0.8pf leading , calculate the field current required.
