Abstract :
To ensure the high voltage gas insulated substations (GIS) reliability while maintaining maintenance costs, it is important to determine the criticality of GIS components and planning maintenance work based on the estimated criticality level. In this paper, the GIS primary system is broken down into indenture levels and subjected to the Failure Mode, Effect, and Criticality Analysis (FMECA) to estimate failures criticality for GIS components. The method is applied to one of the 380 kV GIS installation in the Netherlands. The results have shown that circuit breakers have very high criticality level. Busducts and interconnecting parts, disconnectors, and SF6 bushings have high criticality level. And surge arresters have medium criticality.
