Abstract: Using Gas Insulated Substation in urban areas in the world has been widely popular. After installation, and before being put into service, the GIS must be tested in order to check the correct operation and the dielectric integrity of the equipment. Since it is especially important for GIS, the dielectric integrity must be checked in order to eliminate accidental causes (incorrect fastening, damage during handling, transportation, storage and installation, foreign bodies etc.), which could in future cause An internal fault. Because of their different purpose, these tests should not replace the type tests or routine tests carried out on the transport units and, as far as possible, in the factory. They are complementary to the dielectric routine tests with the aim of checking the completed dielectric integrity and detecting irregularities as mentioned above. In this paper, a novel test set-up and the 400 kV GIS measurement results have been installed for the Sheykh Bahai Substation, Tehran, Iran, are presented. The study of test conclusion shows that it is done successfully in three phases.
