设计了电网接地点监测系统,通过对电网两端电流的测量,经过变换送到计算机内进行计算,判断电网是否发生接地故障,若发生接地故障时,给出接地点的位置,并报警。
This paper designs a monitoring system for the grounding point of the power grid. After measuring the current at both ends of the power grid, it is sent to the computer for calculation to determine whether there is a ground fault in the power grid. If a ground fault occurs, the position of the grounding point is given and an alarm is given.
