sequncy conection

Answer / k.prakashchandra

The above answer is applicable to LT gens connected to bus
bar directly without tr and diff relays.

Answer / ajayiet

if before turning main switch
on r phase is connected to b
phase then we need to see
that where b and y phase are
connected.if y phase is intact
and earlier phase sequence
was ryb then rotation will
change.if all not that is y is
connected to r and b
connected to y nothing
happens.

Answer / k.prakashchandra

Nothing ,if the rotation is the same.In this case if Y of
alt is connected to R phase of AMF and B of alt is
connected Y of AMF, nothing will happen.
