Gas-insulated switchgear (GIS) in particular poses unique and special challenges, including the connection of the test equipment. In today‘s world, where testing is increasingly performed in a non-invasive manner, test systems must offer a certain flexibility and a wide range of testing solutions in order to get proper results in a timely manner.

Substation Erection, Testing and Commissioning Services GIS are getting more popular or say necessary in urban areas or Industries where space is constraint as GIS gives us unique advantage over conventional AIS in terms of saving lot of space. This compactness is achieved by means of SF6 gas instead of Vacuum or Air.

Siemens’ portable power solutions consist of self-contained “plug and play” switching stations built as fully mobile substation on a trailer, a skid, or inside a shelter as an “E-house”. The modules contain all components for a complete substation, from the power transformer and AIS or GIS switchgear to medium- and high-voltage cables, protection, monitoring and control systems, and auxiliary AC and

Superior Dielectric Gas. A gas-insulated substation (GIS) uses a superior dielectric gas, SF6, at moderate pressure for phase-tophase and phase-to-ground insulation.The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in SF6 gas inside grounded metal enclosures.

SF6 insulated Test Transformers are especially designed for testing metal-clad switchgear (GIS) in the factory and in the field, and for testing the other substation equipment. It is also the portable and easy maintenance solution. The SF6 test transformers can be flanged directly to the GIS for testing which make the partial discharge test easy and quick. These systems are particularly suited for on-site tests of GIS
