Video: Generator Protection

       Generator is the heart of an electrical power system. As it converts mechanical energy into its electrical equivalent, which is further distributed at various voltages. It therefore requires a ''prime mover'' to develop this mechanical power and this can take the form of steam, gas or water turbines or diesel engine.

Faults:

Electrical:

Stator insulation failure

overload

overvoltage

unbalanced load

rotor faults

loss of excitation

loss of synchronism

Mechanical:

 failure of prime mover

low condenser vacuum

lubrication oil failure

loss of boiler firing

over speeding

rotor distortion

excessive vibration
