Application of Surge Arrester Against Outage of Distribution Lines due to Breakages of Insulating Conductors

The insulating distribution line breakage is a new problem since insulated transmission conductors are widely used in urban region.Application of arrester can effectively decrease the outages of insulated distribution lines. The effects of installing surge arresters on distribution lines to suppress lightning overvoltage are analyzed, and the protective effect and installing density of arrester are discussed, The possible problems of installing surge arresters are analyzed,too.
