Discharges from moving particles in GIS [gas-insulated switchgear]
IEEE Transactions on Power Delivery, 1998The study of the motion of moving metallic particles in GIS requires a good knowledge of the carried charge of the particle. In this paper, measurements of the charging process of a moving particle, performed in a realistic single-phase GIS, are presented.

Coating and barrier within medium voltage GIS (gas insulated switchgear)
IET Conference Publications, 2009The main purpose of this paper is to investigate ca ses with atmospheric air and hybrid insulation, where solid insulation is used in addition to air. For solid insulation, convenient polymeric materials are used. With hybri d insulation it is typically two options: Coating or barriers.

Verification of the seismic resistance of gas-insulated switchgear (GIS)
IEEE Transactions on Power Delivery, 1993A brief introduction into the background of seismic requirements is given. The test procedures are described, demonstrating the capability of gas insulated switchgear (GIS) to withstand seismic stresses up to highest ground accelerations of 0.75 g. The verification methods for checking the test object after test are described.

Design of a Flexible UHF Hilbert Antenna for Partial Discharge Detection in Gas-Insulated Switchgear
IEEE Antennas and Wireless Propagation Letters, 2023This letter presents the design of a new flexible Hilbert antenna for built-in detection of partial discharges (PD) in gas-insulated switchgear (GIS). The fractal antenna is designed on flexible polydimethylsiloxane (PDMS) material of 124 mm × 122 mm × 0.

A surface resistivity probe for assessing solid insulators in GIS (gas insulated switchgear)
IEEE International Symposium on Electrical Insulation, 2002The changes in surface characteristics after a spacer has been exposed to a large amount of SF/sub 6/ decomposition products for a short period of time, which is similar to conditions during fault repair, are described. The design and construction of a prototype surface electrical resistivity probe which can be used to assess the reusability of ...
