The operation of this embodiment will be described. When the sensor 5 detects a fault current such as a ground fault of the transmission line or a short circuit accident by a known appropriate method, the detector 4 converts the fault current into a fault signal.

Upon receiving the failure signal from the slave station transceiver 1, the master station transceiver unit 7 returns an AKC (acknowledgement) signal for confirmation to the slave station transceiver 1, and at this point the transmission of the failure signal is completed. The slave station transceiver 1 transmits a line disconnection request signal, and when the master station transceiver section 7 receives and confirms the signal, the master station transceiver section 9 transmits a disconnection confirmation signal to the slave station transceiver 1 and ends the information communication operation.

成される。According to the present invention, since the transmitting / receiving section 7 is always in the standby state and only the radio wave detecting section 8 is periodically operated for a short time, the power consumption is small, and the main station side does not need to be connected to the sun. Battery power supply is now available and its installation is easy. Further, since the authenticity of the connection request signal is repeatedly determined at the transmission time intervals, it is possible to prevent the transmitter / receiver from being erroneously started due to electromagnetic induction noise and to further reduce the power consumption. Along with this, the slave station transmitter / receiver does not make an erroneous response and its power consumption is reduced, so that the maintenance of the slave station side solar cell is simplified and a long service life is achieved.

どの損傷も防止できる。Furthermore, since information transmission between the failure detection slave station side and the central master station side is performed wirelessly, particularly by radio waves of a specific low power radio assigned frequency, the transmission line of an optical cable or the like is conventionally used. The work of securing the installation site and laying the transmission line is also unnecessary. Further, since the failure detection slave station is electrically insulated from the tower and various devices of the central master station, it is possible to prevent damage to the slave station sensors and transceivers in the event of a lightning strike on the tower.
