Aimed at temporary grounding wire detection problems in distribution network, some factors influence the detection precision, on this basis, an electromagnetic transient simulation model for temporary grounding wire detection was established based on PSCAD/EMTDC platform, the model simulates the actual process of grounding wire detection work. In the simulation model, the impact of signal frequency on the precision of grounding wire detection in distribution maintenance lines was studied. The simulation results show that different frequency of injection signal has impacts on the grounding wire detection due to the distributed capacitors and lines inductances. Based on simulative analysis, a medium frequency range, especially the inter-harmonics, were suitable for signal injection detection. Meanwhile a threshold current method was proposed as detection criterion, and the method was simple and practical.
