Abstract

Very fast transient overvoltage（VFTO） is produced when the disconnector operations in gas insulated switchgear（GIS）

which has a great impact on the power system stability and the safety operation of electric equipment.The simulation technology is an important research method for studying the characteristics of VFTO. Studying the development and parameter variation of switching arc of disconnector in GIS is significant for obtaining the standard VFTO wave form.This paper elaborates almost all switching arc models of disconnector in GIS for the current VFTO simulation.Traditional switching arc models

improved switching arc models and the experimental research of arc characteristic are discussed and summarized.At the same time

the advantages and disadvantages of the different arc models are analyzed.Finally

the trend and further problems of GIS switching arc model for VFTO simulation are overviewed.This paper aims to provide a systematic theory platform for discussion and a beneficial reference to peer scholars.
