High impedance grounding fault detection for distribution networks based on fault component principle

High impedance grounding fault detection for distribution networks based on fault component principle

The short-circuit current value of distribution network is small when high impedance grounding faults (HIGFs) occur,which cannot be detected tripped by the traditional over-current protection devices. If short-circuit cannot be tripped in time,it will lead to serious results. To solve the above prob...
