Special problems in gas insulated substations (GIS) and their effects on indian power system
2012 IEEE International Conference on Power System Technology (POWERCON), 2012The increase in demand for electricity and the growing energy density in the metropolitan areas have made it necessary to extend the high voltage network right up to the consumer. Gas insulated substations provide a best solution to the above problem and have been functioning for more than 30 years around the world.

This paper presents the EMC (Electromagnetic Compatibility) philosophy applied to design the grounding systems of GIS Insulated Substation - GIS indoor substation. The grounding systems are characterized by the following subsystems: Main Grounding grid (60 Hz Grounding System), Equipotential Grounding grid (HF Grounding system) and Lightning Grounding ...

i-manager's Journal on Power Systems Engineering, 2016
Mitigation and analysis of very fast transient over voltages (VFTO) is very important in gas-insulated substations (GIS). In this paper a power transformer rating of 1500 MVA in 1000 kV GIS has been considered and different techniques for mitigation and analysis of VFTOs at the transformer are applied and the same results are analyzed by the ...

Solutions of essential problems of gas insulated systems for substations (GIS) and lines (GIL)
Proceedings of the 7th International Conference on Properties and Applications of Dielectric Materials (Cat. No.03CH37417), 2004GIS and GIL are applied since several decades and proved to be very reliable and safe components of the power supply system. Extensive fundamental research was necessary for the development of the technology. Out of countless problems three are chosen to demonstrate the numerous phenomena, which had to be investigated. These are the flashover to ground
