Neutral is the point formed by connection of 3 phase windings of any 3 ph Xmr/motor or generator. In case of solidly grounded system this neutral is earthed. IN case of Generators it is earthed through impedance to limit fault current.
Earth is a system which provides a path for current to flow into the earth. It acts as a Protection by providing early isolation of faulty section in case of any fault.

kindly tell me how the load on generator increase by just increasing the fuel of prime mover, as if for exampple 20 MW gen set is synchronized the load ramps from zero to 20 MW gradully and during this procress only fuel of prime mover increases. Which thing determines the load on generator with respect to fuel
