Abstract

Grounding wire detection is an important work in distribution network, especially before recover the power supply of transmission lines. Aimed at grounding detection problems, a detection scheme based on current shunt principle was proposed and before the detailed discussion of detection scheme, several factors impact the detection precision were simulated through the PSCAD/EMTDC platform, the factors include the access of transformer, branches in transmission line, common-tower transmission lines, the earth resistance and two grounding points. The simulation results show that the factors have little impact on grounding wire detection and a variable frequency should be selected. The proposed detection scheme based on current shunt principle shows a better practicability in three-phase, two-phase and single-phase grounding situation, as well as the inter-phase short circuit. The simulative researches on the influences of grounding wire detection provide a guiding significance for the actual grounding detection work.
