The neutral point of 25MVA, 11kW alternator isgrounded through a resistance of 5Ω, the relay is set of operatewhen there is an out of balance current of 2A. The CTs used have aratio of 1000/5. Calculate (neglect resistance ofalternator):
i. The percentage of stator winding protected against earthfault.
ii. The minimum value of earthing resistance to protect 95% of thewinding.
