PURPOSE:To transmit a control signal by using a transmittable part of a transmission line when a part of the line for transmitting a control signal of a switch of a power distribution line becomes impossible to transmit. CONSTITUTION:A master station 5 sends a control signal to a slave station 3 through a transmission line 4, information segment switches 6, 6' to control a switch 2 installed on a power distribution line 1. When a fault occurs at the line 1, the switches 6, 6' separate front and rear lines of the line 4. A temporary master station 7 sends information to be sent from the station 6 to the switch 6 through a second transmission line 9 and a repeating station 8, and the switches 6, 6' sequentially transfer the information sent from the temporary master station to next information segment switch. |
