Study of transient zero-module current measurement of single-phase earth fault in neutral non-effective grounding system
摘要
Abstract
A new method using magnetic field induction to measure transient zero-module current of single phase earth fault in neutral non-effective grounding system overhead lines is proposed. The paper analyses the characteristics of magnetic field around the overhead lines in detail, and the results show that the relationship of magnetic field under overhead lines and the transient zero-module current is linear, so transient zero-module current can be measured by inducting the magnetic field. Using a Hall probe magnetometer to induct magnetic field for fault transient current measurements is proposed, and some key techniques of practical application are expatiated. Simulation and experimental tests verify the correctness and feasibility of the proposed method.关键词
