Analysis of Technical Performance of Combinatorial Over-voltage Protector

This paper introduced the development of lighting arrester. It analyzed the fundamental principles and characteristic parameters of several combinatorial over-voltage protectors. The paper mainly approached their all-sidedness and reliability as well as self-safety. Its intention was to look for a certain over-voltage protec- ting device which can fit in our country’s electronic power development by analyzing the advantage and shortcoming of the protector.
