In 1 of the three phases,any of one phase was get affect
due to unbalance of cable or busbar champer with breaker
isolator connection get loose,it will reflect by no current
and less voltage on that particular phase and utilisation
of equipement also shown problem on that phases. i was
faced this problem in previous plant as from lighting
