| Abstract: |
| The characteristics of Metal Oxide Surge Arrester (MOA) are introduced first, its applications in power system are then presented. The causes of switching over voltage which are occurred in several typical circuits are analyzed, and the over voltage protective devices based mainly on MOA and their connection modes are discussed. The applications of MOA'S Y scheme(TBP) in non direct grounding neutral system are finally expatiated. The purpose is to roundly introduce the applications of MOA in power system. |
| Key words: MOA,TBP,switching over voltage,non direct grounding neutral system,Y scheme |
