  • Gas Insulated Substations Advantages Disadvantages

    Gas Insulated Substations (GIS) are differ from Air Insulated Substations (substations we usually see) such that all the substation equipment such as busbars, circuit breakers, current transformer, potential transformers and other substation equipment are placed inside SF6 modules filled with SF6 gas.
