a distribution transformer(3 phase)supplying 440volt per
phase.now suppose one of phase voltage(230volt) becomes
zero.what will be the cause ?
Answer Posted / 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
