Example Embodiment
[0025] The invention includes a fault indicator, a data concentrator and a master station.
[0026] The short-distance wireless communication technology is used between the fault indicator and the data concentrator, and the data concentrator receives the signals of multiple fault indicators and sends them to the master station; this can reduce the communication cost. This kind of communication method is now widely used, and here is only a method for implementing communication between devices between systems, and it is not the protection content of the present invention. The master station is the processing center of the system. The special feature of the present invention is the cooperation between the fault indicator and the master station.
[0027] The working principle of the present invention will be further explained below with reference to the accompanying drawings. The fault indicator enters the working state after being installed on the overhead line or the cable line.
