Abstract  

With the gradual increase in the number of installation of auxiliary equipment transmission line with backbone transmission network in recent years, the research of safety and applicability about conventional method for live working on the installation is still relatively small. Therefore, this paper proposed a method about installation of auxiliary equipment line by ladder into potentiometric, modeled the equipments in the operating area and simulated the parameters of space potential and electric-field distribution by utilizes harmonic response analysis and finite element analysis theory before and after into the electric field. The result showed that the method has mentioned in the plan can meets safety requirement when equal potential operator performed the shift of potential through insulating ladder from main materiel of the tower where directly below the wire and 0.6 meters to the lower bundle conductor.
