The epoxy insulators in dc gas-insulated transmission lines (GIL) tend to accumulate surface charges, which causes insulation flashover. Increasing the conductivity of resin, can restrain accumulation charges on insulator, is a potential method improve performance GIL insulators. polymer dielectric strongly influenced by charge trap characteristics polymer. In this work, we introduce chlorine w...

This paper presents a numerical computation method for determining the magnetic field of high-current busducts of circular cross-section geometry, based on the subdivision of the busduct phase conductors and screens into the conductor filaments and the subsequent application of the mesh-current method, with the aid of the geometric mean distance method. The mathematical model takes into account...

The paper deals with the possibility of installing a double-circuit Gas Insulated transmission Line (GIL) in the pilot tunnel of the new planned railway galleries Fortezza-Innsbruck. The high GIL power ratings with very low power losses would allow a strong and highly efficient energy exchange particularly useful for the future European Market and could represent a new fundamental step in recon...

Abstract. Close-Range Photogrammetry (CRP) technology advanced rapidly along with the development of camera sensors. CRP has many advantages over other methods in terms technical data acquisition, product quality, and cost. Because these advantages, method can be used various applications. In this study, is to monitor deformation SF6 Gas Insulated Line (GIL) object between two substations Indon...

Abstract The surface charge accumulation on the basin insulator is a particular problem in high‐voltage direct current (HVDC) gas insulated switchgears (GIS) and transmission lines (GIL), which restricts development application of extra/ultra (EHV/UHV) technology. distribution anti‐flashover performance are closely related to shape. To obtain optimal insulator, shape optimisation model based ar...

Gas-insulated substations (GIS) have different specifications in proportion to air-insulated substations. Transformer failures related to lightning and switching are often reported in the gas insulated substation (GIS). This problem is the voltage magnifications due to reflections of switching and lightning surges at various junctions within the GIS. thereby overvoltages in GIS are more importa...
