Answer Posted / ramachandran.s
to limit the fault current so as to minimise the fault
current. the system can run with a single fault. when
second earth fault occur the system will trip of fail. so
when the first fault occur corrective step has to be taken
to rectify the fault. thus neutral is earthed thro'
resistance or reactance will increase the relability of the
system

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?
