IEEE Transactions on Power Delivery, 2017
Several methods have been proposed and investigated so far on mitigation of very fast transient overvoltages (VFTO) in gas-insulated switchgear (GIS). The state-of-the-art methods are primarily based on dissipation of the energy associated with electromagnetic waves that the VFTO originate from and are composed of.

IEEE Transactions on Dielectrics and Electrical Insulation, 2007
Gas insulated switchgear (GIS) has been increasingly being used in recent years and high reliability and rational insulation design are required. This research provided V-N characteristics (the dielectric breakdown voltage versus number of repetitions characteristics) regarding the internal insulation and creeping insulation of the epoxy spacer, which ...

Advanced Metal Oxide Surge Arrester for Gas Insulated Switchgear (GIS)
IEEE Power Engineering Review, 1984SF6 gas has outstanding dielectric strength and heat transfer property. This suggests that zinc oxide (ZnO) elements whose value of E in E-J characteristic is higher than the value of the elements used in a porcelain type arrester is suitable to metal enclosed metal oxide surge arresters (MOA) for gas insulated switchgears (GIS). Several kinds of newly

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 ...

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.
