This paper presents the advantages of metal oxide arrester comparing with other types arrester
and discusses the principle of coordination between MOA and protected insulator string.The result of analyzing the voltage-time characteristics of MOA and insulator string shows the effectiveness of protection by MOA is more than 99.993%.Then
the conclusion is reached that the effect of MOA preventing overvoltage is remarkable in overhead power transmission lines.Finally
primary technology parameters of MOA are suggested.
