Dynamics of Metallic Particle Contamination in Gas Insulated Substation (GIS)
This paper analyses the movement of free conducting particles inside a single phase Gas Insulated Bus duct(GIB).A two dimensional mathematical model was proposed for determining the movement pattern of metallic particle in GIB by considering all the forces acting on the particle like gravitational, drag and the electric field forces.

Design and Characterization of a Magnetic Loop Antenna for Partial Discharge Measurements in Gas Insulated Substations [PDF]
A recent investigation explored a new measuring concept used in partial discharges (PD) measurements in gas insulated substations (GIS), consisting of a magnetic loop antenna. The sensor's frequency response was characterized up to some tens of MHz. This

Breakdown Mechanism of Different Sulphur Hexafluoride Gas Mixtures
Sulphur hexafluoride (SF6) gas and SF6 gas mixtures are widely used in gas-insulated systems (GIS) because they have good dielectric and thermal properties.

Analysis of Very Fast Transients Using Black Box Macromodels in ATP-EMTP
Modelling for very fast transients (VFTs) requires good knowledge of the behaviour of gas insulated substation (GIS) components when subjected to high frequencies. Modelling usually takes the form of circuit-based insulation coordination type studies, in
