Western Ky.
If it is wired correctly and there are no grounds in the peckerhead the winding insulation is breaking down. At 2000 hp I would assume it is a 13800 volt motor. When the winding insulation breaks down the voltage will escape through the bearings. Has the motor been megged or hi potted?
Why would an electric motor ground through the shaft?
