Answer / k.prakashchandra

If other 2 phases are OK ,it may be due to open circuit in
that phase.If other 2 phases show 50% ,it may be due to one
phase missing in the primary of substation power transformer

Answer / ambai algates

if 1 phase open the unbalance current is flow through
neutral , so its exit the setting bkr trip .if there no
load you got 230v only in phase to open phase

Answer / akash`

check your high tension line d.o.if three d.o. is ok then
substation problem not coming one phase means single phasing
problem call it

If symmetrical fault occurs at the terminal of a synchronous motor then how the motor will act...explain it..
