Gas turbine generator protection.
Protection against generator motoring is designed to protect the prime mover as opposed to the generator.
Such machines may be employed for variable speed motoring in pumped storage generation schemes or for starting a large gas turbine prime mover.
A downstream turbine on the same shaft as the compressor.
This form of protection can provide earth fault protection when the generator is at standstill prior to run up.
These are the main factors which make protection necessary for the generator or alternator even when properly used a machine in its perfect running condition does not only maintain its specified rated performance for many.
