Partial discharge in Gas Insulated substations (GIS): A development and engineering perspective

2013 12th International Conference on Environment and Electrical Engineering, 2013
GIS and its allied subsystems are always expected to function and work with extremely high level of reliability. These substations contain several dielectric interfaces and combinational insulating medias. The GIS may be subject to Partial discharge activity may initiate in some conditions in the GIS modules considering its varied operating conditions ...

Comparison Between Suppressing Approaches of Very Fast Transients in Gas-Insulated Substations (GIS)

IEEE Transactions on Power Delivery, 2013
In this paper, first transient waves in the gas-insulated substation (GIS) are analyzed and methods for suppression of very fast transients (VFTs) in GISs are introduced. For suppressing VFTs, four methods are presented, including suppression by terminal components, capacitance components, adopting a resistor-fitted disconnector, and ferromagnetic ...

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).

Gas insulated substation GIS

2008 IEEE/PES Transmission and Distribution Conference and Exposition, 2006
Reliable and economical power transmission and distribution are key functions for the future electric power supply. Gas insulated switchgear is used in industrial areas to fulfil high-energy demands by space saving design with a minimum of cost. Only SF6 insulated switchgear is able to fulfil these requirements.
