So that the incoming and reference phases have common
neutral which establishes relationship between them

Answer / kusuma

Pl. clarify, closing of neutral contactor is depending of
whichever DG satrt first or always master neutral
contractor? In this condition what happen other neutral
current

Answer / rajagopal.d

master is running in constand load its have stablising
capacity, if new load is coming slave is taking and
transfer graduly to master

Answer / jignesh

may be to prevent the whole system from tripping when none
master Dg fails.
