transistor are mainly current driven whle for switching are
done at high frequency and high voltage. thus devices like
SCR,IGBT,MOSFET,etc are used.
transistors are employed in small ckts

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?
