By detecting fault information such as characteristic current and electric field of the line, the fault type and location can be quickly determined, and an online network diagram can be generated in real time to facilitate user line fault operation and maintenance....

By detecting the current, voltage, switch position, and fault characteristics of the circuit, distributed intelligence is adopted Comprehensive algorithms such as energy and centralized FA are used to achieve automatic fault isolation and power restoration, reducing the size of the system Power outage range, improve the reliability of the power system....

Compared with the distribution network, the structure of 110kV and above high-voltage transmission network is simple. Generally, there is no branch line and no distribution transformer. The occurrence rate of overhead line operation ground fault is relatively high, the line support is generally pole tower, and the cement pole is less, so the ground resistance phase after the ground fault occurs...
