摘要：
The existing high impedance fault (HIF) models cannot precisely describe the slow varying characteristics of tree-contact single-phase-to-ground faults (TSFs). A simulation model for TSFs was established based on the physical mechanism. Test results show the nonlinearity characteristics of the transition resistance in short time and the slow varying characteristics in long time are well matched in the calculations. Based on the built model, a detection method was proposed using the long-time variation trend of the magnitude of the fault vector. Simulations show the fault detection sensitivity of the method is over 17kΩ. A 51kΩ TSF was detected in field test. © 2021 Chin. Soc. for Elec. Eng.
