Lightning Protection Performance of 500 kV Compact Transmission Lines

doi:10.11930/j.issn.1004-9649.2013.5.38.6

Abstract

Abstract: Lightning protection of compact transmission lines is very important for their safety operation. A statistic analysis of the lightning protection performance of compact lines in the north Hebei area indicates that the compact lines have obvious advantages over the conventional lines in lightning protection performance. Due to its special tower window structure, shorter air gap and lower lightning impulse flashover voltage, the compact line is higher than the conventional line in back striking trip-out rate.

Key words: 500 kV, compact transmission line, lighting protection performance, back striking, shielding failure
