in three phase with neutral connection, what will happen,if
the neutral is in open condition with single phase
distribution panel
Answer Posted / pillay
It depends where the neutral is in
open condition.
when all three phases are loaded with
single phase load and the main neutral
is in open condition than the voltage
across the load will vary according to
the load and the voltage can be as high
as phase to phase voltage thus resulting
in damage to electrical equipments, but
if they are loaded symmetrical than the
phase currents are balanced internally
and the voltage across the phases are balanced.
