Hi all,
I face a peculier problem. Before switching on the PDB i.e. main contactor of PDB, the voltage in all the three phases is balance 240V. But as soon as the main contactor is made on, the voltage in one phase shoots up to 260-270 V and in phase it drops. I have checked the earthing and any loose connection in the panel. But everything is alright. Can any one give any clue?
