| Abstract: | This paper analyses the reason that induction voltage induces on the non-energized lines of 500 kV double circuit transmission lines and calculates the induction voltage by simulation.The effects of all factors such as the position of ground wire and the value of earth connection's ground resistance,cross section of the lines,loads,lines throwing in and switching off on the energized lines,the tower ground resistance are analyzed.The conclusion is that the position of ground wire and the value of earth connection's ground resistance are two of the most important factors. |
