| Abstract: | The paper analyzed the lightning performance of back striking and shielding of overhead transmission lines in Zhejiang Province,and assessed lightning trip-out rate of overhead lines of 500 kV,220 kV,110 kV,which have two lines on pilot study. The results of assessment are in good agreement of the actual lightning trip-out rate of lightning trip. The method of analysis of the lightning performance and assessment of lightning trip-out rate of overhead transmission lines has practical significance. |
| Keywords: | overhead transmission lines analysis lightning trip-out rate assessment |
