Description

technical field [0001] The invention relates to the technical field of relay protection devices, in particular to a 500 kV line protection outlet loop test device. Background technique [0002] With the rapid development of the power system, the scale of the power grid is growing day by day, and the network structure of the power system is more complex. It is particularly important to improve the safe operation level of the power system. Due to the particularity of the power system, the occurrence of electrical faults is inevitable. During the operation of the power system, if a local power grid or electrical equipment accident occurs and cannot be effectively controlled, it will inevitably cause damage to the stability of the power grid and a large-scale blackout accident; modern large power grids are more dependent on relay protection. The requirements for the correct rate of its movements are higher. [0003] The relay protection device is an important part of the power...
