| Abstract: | Lightning disturbance is a main prob-lem that in-fluences the operation safety of the transmission lines in Shenzhen area. Installa-tion of line metal-oxide arrester (MOA) on transmission section with frequent lightning can improve the lightning withstand level of the transmission lines. The development and basic principle of MOA are introduced. The opera-tion experi-ence of MOA application in 110 kV and 220 kV transmission lines in Shenzhen power net-work in re-cent years is summarized, the effect on reducing lightning stroke trip-ping rate is analyzed, The site-selection, installation and mainte-nance of MOA are discussed, existing is-sues in adopting MOA and proposals are presented. |
