Japanese Patent JPWO2022153541

A1

Provided is a system used when a power-source-side circuit from a power source and a load-side circuit extending toward a load, a receptacle, and the like are electrically connected via an electric power apparatus, the load operating with electric power supply and being exemplified by lighting facilities/equipment, air conditioning facilities /equipment, freezing/refrigerating facilities/equipment, and production facilities/equipment, the receptacle serving as an electrical connection part for supplying electric power to the load and the like, the electric power apparatus being exemplified by a power receiving/transforming facility, a switchboard, a distribution board, an electric light board, a power board, a control board, and a junction box, which are provided with electric equipment such as a master main braker and an electric leakage braker. The system saves labor by enabling automatic switching of ON/OFF of each load and automatically metering electric power consumption in the load to enable automatic electric-power-consumption calculation. The system further prevents electrical accidents which leads to fire from occurring by, for example, detecting bolt looseness and insufficient insertion into the receptacle in a screw-bolt-fastened connection part in the electric power apparatus and electric leakage due to dust adhesion in the screw-bolt-fastened connection part and the like.
