Abstract

Abstract PURPOSE:To detect the position of a flashover steel tower at a remote position such as a wire maintenance center and a control center by transmitting the output of a flashover detection sensor fitted to the steel tower to a place where the position of the flashover steel tower is detected through an optical fiber. CONSTITUTION:Flashover detection sensors 3a1 and 3a2, and 3b1 and 3b2 are fitted to steel towers 2a and 2b of the power transmission line as an object of flashover detection. Further, electrooptic converting circuits 5a and 5b are provided to turn on a group of light emitting diodes corresponding to binary codes of addresses given to the steel towers previously or one light emitting diode combined with a branch circuit according to outputs of those sensors. Then, if a flashover occurs to, for example, the steel tower 2a, the sum output of the sensors 3a1 and 2a2 is inputted to the converter 5a and converted into a light signal, which is guided to a signal fetch circuit 7a through an optical fiber 6a and transmitted to the wire maintenance center or control center through the optical fiber incorporated in an optical fiber compound overheat earth-wire 1.
