Abstract :
In 1967 the first gas insulated metal-enclosed switchgear went into service in the German 110 kV network. Today GIS technology is successfully used for voltages up to 800 kV. GIS is an attractive alternative to conventional air insulated substations (AIS) because of the increased availability, reliability and the reduced life cycle costs. The author discusses the following aspects of SF6 GIS: enclosures; circuit breakers; disconnectors and earthing switches; voltage and current transformers; connection modules; type testing; routine testing; maintenance; and layout and installations
