Abstract

Operating condition of a metal-oxide varistor（MOV）is analyzed considering the operating principle of series capacitor bank. The characteristics of the MOVs in the series capacitor banks for TCSC and FSC are compared

and the overvoltage protection of MOV and control measures are discussed. The key technologies for design of MOV are described

including protection level

energy withstand

power-frequency voltage stability

current distribution

and special release ability of short circuit current. According to the requirements in a bids invitation for compensation project of a 500 kV AC power system

two kinds of MOV structures with composite shield and porcelain shield were designed

and the products have passed the type test in the China Electric Power Research Institute

indicating that they meet the engineering requirement.
