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
