Analysis on Lightning Protection Effect of Line Surge Arresters on a Compact Designed 500 kV Chang-Fang Transmission Line |
| |
| Abstract: | The lightning
withstanding level of 500 kV Chang-Fang compact designed transmission line can be greatly
improved with installed line surge arresters on transmission towers． The 500 kV line
surge arrester with the selected applied voltage ratio of 0．9 can withstand lightning
discharge current and absorb lightning energy in case of direct strikes on to wers．When
the span of the line increases，the lightning withstanding level can be increased by
installing line surge arresters． |
