FIELD: electricity.
SUBSTANCE: system includes operation control unit (20), alternating-current cable (16) attaching machine (30) to the operation control unit and electrical short-circuiting device (26). This device is connected to outputs of the operation control unit on the cable side, and short-circuiting of these outputs is based on the detected overvoltage.
EFFECT: providing protection against overvoltage determined by self-excitation.
