A 2500KVA, 6,600 volts, three-phase wye connected alternator has an effective resistance of 2 ohms and a reactance of 10 ohms per phase. Calculate the per cent voltage regulation at full-load for 0.866 lagging power factor a) Using I phase as a reference vector. b) Using V phase as a reference vector.

A synchronous generator is rated 645 MVA, 24 kV, 0.9 pf lagging. It has a synchronous reactance 1.2 . The generator is feeding full load at 0.9 pf lagging at rated voltage. Calculate: (a) Excitation emf (E,) and power angle 8 (b) Reactive power drawn by the load Carry out calculations in pu form and convert the result to actual values.

A 1500KVA, 8KV, three-phase wye-connected alternator has an effective resistance of 0.502 and a reactance of 62 per phase. It delivers full-load current at 0.8 lagging power factor at rated voltage. What will be the terminal voltage for the same excitation and load current, if the power factor is 0.8 leading?

The topic is electromagnetic fields. I need the expert's solution to the question in handwriting.
