What is static frequency control used in gas turbines

Answer Posted / jithu toms

while starting gas turbine(generater) ,it should be started
as an induction motor,so need to adjust frequency to obtain
desired speed, after that by combustion of gas it will run
and induction principle will cut off..This frequency
controlling is done by sfc.

Assuming that a dedicated neutral earthing transformer is provided for each GT generator, when the two generators are running in parallel, has consideration been given that the earth fault current from one generator stator winding be split between the two neutral earthing transformers? If so, what adverse impact will this have on the operation of the 59N and 27TN devices?
