PROBLEM TO BE SOLVED: To perform the remote monitoring of the opening and closing state of a switch in the vicinity of the boundary between business offices by laying a special transmission path between business offices (between monitor sections). SOLUTION: The information on the opening and closing states of the switch S4 in a business office A (self monitor area) adjacent to the power distribution system of a business office B (other monitor area) and the information on the current application state of power distribution blocks K3 and K4 leading to both sides of the switch S4 are transmitted to a central processor (not shown) through a transmission path 13-1 from a control slave station L4. The central processor judges the opening and closing state of the switch S5 of the power distribution system in other monitor area adjacent to the switch S4 from the transmitted information as the cases 4-6 of 2(c). This way, the opening and closing state of the switch in the vicinity of the boundary between business offices can be monitored by the judgment result. |
