  • Hybrid Switchgear - electricalfundablog.com

    Here AIS stands for Air Insulated Switchgear and GIS stands for Gas Insulated Switchgear. Hybrid switchgear is a condensed switchgear which is mainly used in the renovation and extension of substations with AIS based switchgear where such modifications are required to be accomplished keeping the substation in service.

  • End of life estimation of HV switchgear and GIS

    Gas-insulated switchgear (GIS) technology was introduced in the late 1960s and is now available for all voltages up to UHV. Therefore the first generation of 123 kV GIS technology up to 1978 and of 420 kV GIS up to 1988 are considered separately. The population in question amounts to 700 bays and 3750 bay-years at the 123 kV level and 130

  • Mechanical defect identification for gas‐insulated

    Mechanical defect is an important reason for the failure of gas‐insulated switchgear (GIS) equipment. Based on the time‐frequency characteristic vibration signal analysis on five kinds of mechanical defects, a novel intelligent algorithm model combining complementary ensemble empirical mode decomposition (CEEMD) and genetic algorithm improved kernel fuzzy mean clustering (GAKFCM) was

  • Health index and risk assessment models for Gas Insulated

    2020-5-1The failure rate of Gas Insulated Switchgear (GIS) operating under tropical conditions is about twice the value reported by the third CIGRE’s survey in 2007. Three major failure modes that lead to catastrophic failure of a GIS in tropics are the insulation breakdown, the primary joint-conductor failure, and the driving mechanism failure.
