Gas Insulated Switchgear evacuation for high voltages

High Voltage Switchgear . A high voltage circuit breaker. High voltage switchgear, otherwise called high tension switchgear, handles high voltages. As the voltage level increases, the intensity of arcing generated due to switching operations also increases. There are two types of classifications for high voltage switchgear: Gas-insulated

  • High voltage gas insulated switchgear: an overview | IET

    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
