In order to fully realize the specific distribution of network equipment, clarify the topology network of network equipment, improve the intelligent perception ability of power grid, eliminate potential safety hazards in time, and ensure the stable and healthy operation of power grid. In this paper, a topology sensing technology based on N-line is proposed. According to the principle of current transmission along the circuit with minimum impedance , Modern microcomputer processing and control technology is adopted ,The characteristic current signal injection technology based on N-line is adopted to reduce the impact on the network equipment. It can be easily and quickly connected to the transformer in the substation area and the branch box at all levels, realize the intelligent topology identification of the network equipment in the substation area, facilitate the locking of the fault point, and cut off the power supply at the fault point at the first time, Timely repair faults to ensure normal and efficient power supply. At the same time, it can also effectively promote the rapid development of ubiquitous power Internet of things.
