Abstract :
Gas insulated substations (GIS) operable at medium voltages have been in use for some time. In view of their compactness, GIS possess a high degree of reliability of operation in power utility systems. Among the more important problem areas concerning GIS is the adverse effect of metallic particle contamination of the gas medium. In order to be able to improve the operation of GIS in the inevitable presence of particles, a novel method by which the particles are passivated has been suggested. Studies have been conducted to obtain optimal value of conductivity of the coating material to have a better performance
