Application of gas insulated transformers to underground

Abstract:Concentration of population and business activities result in high electricity demand in urban areas in Japan. Underground or indoor substations are required to comply with the increasing demand for electricity. Electric utility companies in Japan studied this situation and came to conclude that underground or indoor substations applying gas insulated transformers (GIT) together with gas insulated switchgears (GIS) would be the best solution.Get price
