We have a capacitor bank connected in wye float ground on a 23kv line. but its body were grounded.
We have performed a hipot testing and test show that they are ok for installation.recently the fuse on phase B blow. We replaced the blown fuse but at the moment of restoration of that phase, the phase A also blow.The rated voltage of capacitor is 14.4kv.
Can anyone give me an idea whats the cause of fuse blowing. There was no abnormalities in the line when we tried to restore the bank. Thanks and Good day.
