Effect of various design parameters on the performance of Gas Insulated Substations (GIS) using Charge Simulation Method

2011 Annual IEEE India Conference, 2011
The Insulation Performance of Compressed Gas Insulated Switchgear and Gas Insulated Transmission Line(GITL) systems can be substantially affected by the presence and movement of metallic particle contaminants. SF 6 gas is the main mode of insulation in Gas Insulated Substations(GIS).

Mitigation and Analysis of Very Fast Transient over Voltages (VFTOs) of Transformer in 1000 KV Gas-Insulated Substation (GIS) Using Wavelet Transform

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), 2004
GIS 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
