Could Vacuum Contactor cause motor failure?
Could Vacuum Contactor cause motor failure?
(OP)
About a month ago I replaced an old 2300 volt oil immersed motor starter lineup with new vacuum contactor starters. One of the motors has since failed to ground and I was wondering if the failure could have occurred because of a transient caused by the fast interrupting time of the vacuum contactor and the long motor lead length. The motors are about 1 mile from the starters and are 125HP submersible well pumps.
