REAL-TIME DETECTION/RECOVERY SYSTEM OF POWER LINE FAILURE IN POWER DISTRIBUTION SYSTEM AND CONSTRUCTION METHOD THEREFOR

WIPO Patent Application WO/2018/131797

A1

Disclosed is a real-time detection/recovery system of a power line failure in a power distribution system, which immediately alerts, shuts off, and recovers power in real-time when a disconnection, a resistance increase, a contact failure, a half-disconnection, or a short circuit occurs in a single-phase power supply side of a three-phase or single-phase power distribution system. A power distribution system, according to one aspect of the present invention, may be provided with one or more of a power supply side detection/recovery device and a load side detection/recovery device. The power supply side and load side detection/recovery devices may recover, shut off, alert, notify, or control an electrical failure in a power supply line of a single-phase or three-phase power supply by forming a neutral point with an element electrically/electronically connected to the single-phase or three-phase power supply to ground the neutral point to the ground or detect a potential difference between the neutral point and the ground.
