10KV Zno surge arrester for distribution
Zincoxide (ZnO) surge arrester is one of the important apparatus for GIS in the power system and its normal running has significant influence on the performance and reliability of GIS.
The Metal ZnO Arresters (MOA) are important over-voltage protection device. They are widely used in electric power system due to their excellent nonlinear and high surge absorbing capability. And it is one of the most important equipments in electric power system. Whether its running status is good or not directly affects other equipments in sub stations.
Using the ZnO surge arrester to prevent the shunt capacitor from overvoltage is one of the most efficient and reliable measures, and in many cased it is a necessity.
