Abstract
Some implementations include an apparatus configured to, in a wellbore, eliminate voltage on one or more first conductors that are electrically connected to a surface-based power source. The apparatus may include a shorting ring electrically connectable to the first conductors and configured to electrically short the first conductors upon establishing an electrical connection with the first conductors. The apparatus may include a solenoid assembly to actuate in response to power on the first conductors from the surface-based power source. The apparatus may include a pin slider assembly connected to the first conductors and configured to move, in response to actuation by the solenoid assembly, between an electrical connection with the shorting ring and an electrical connection with one or more second conductors that have an electrical connection with a permanent magnet motor winding in the wellbore.
