Abstract: In order to improve the safety of entering the equal potential mode of live work on ±800 k V transmission lines,this paper establishes a path optimization analysis model based on fuzzy analytic hierarchy process（FAHP）by comprehensively considering the main factors affecting the optimization of entering path,and selects the best and several commonly used methods for entering equal potential mode to calculate their weights. Combined with the calculations,the different methods are comprehensively evaluated. It is concluded that hanging basket of 45 degrees is the optimal path of entering the equal potential mode,providing data reference for the safety protection of ±800 kV UHV live working.
