E – 1685 Gas Insulated Substation (GIS) Testing and Applications

To provide the function and safety the GIS installation for which it was designed, the GIS has to be tested. The testing procedure is done to confirm the technical information as well as safe operation of the GIS installation over its life duration. Related to the GIS installation use, the main tests are dielectric tests, short-circuit tests, mechanical tests, and temperature rise tests.

Two different test processes are used: type tests that are also known as design tests, and routine tests, that are known as factory or production tests. While type tests confirm the functions of one GIS type after product development, routine tests check that each manufactured item functions according to the technical demands to which the GIS installation is supposed to adhere.

This course is suitable for electrical engineers with a desire to understand the fundamentals of GIS technology type and routine tests. Upon successful completion engineers will be able to address main GIS test types, their principles, required equipment and expected results. Reference to the valid international standards and procedures is provided.
