In gas insulated switchgear(GIS) SF6 gas is widely in use because it has good electrical insulation and arc interruption capabilities. Due to environmental constraints the desire to use alternative gases is continuously growing. This paper focuses on dry air as an alternative gas

The design constraints of gas insulated switchgear(GIS) are changing due to an increasing power demand and decreasing available floor space for substations. Ideally, new GIS should operate at a higher nominal voltage with a minimal or no increase in size. Another ongoing developm

Electric power consumption has increased over the years while the available space for substations has become smaller. Newly designed gas insulated switchgears (GIS) have to be smaller and have to operate at a higher system voltage. Furthermore, the urge to decrease the use of SF6

Nowadays in Gas Insulated Systems (GIS), SF6 is often used as insulating medium. Due to the fact that SF6 is a greenhouse gas with a very high global warming potential (GWP), alternatives have been searched for over the last years. In particular, SF6/N2 gas mixtures have been ext
