The increasing demand for high voltage direct current (HVDC) technology requires the
adaptation of gas insulated switchgear (GIS) or lines (GIL), which were originally developed …

Many electrical insulation systems use a combination of gaseous and solid dielectrics. This
article describes a model, implemented in COMSOL Multiphysics, for simulating the electric …

DC field measurements of the electric field around a cable termination have been
performed. The field variation along the surface as well as its time development after voltage …

Within the framework of this thesis an experimental setup for measuring surface potentials
that are due to accumulated surface charges on gas insulated HVDC model insulators is …

This paper focuses on the time constant of transient AC–DC field distribution of DC GIS. As
the resistive field depends on the conductivity of solid and gas surrounding in the GIS, these …

Different methods are developed for mitigation of ferro-resonance in high-voltage gas
insulated substations (GISs). The main components, which have impacts on probability of …

Dimensioning of HVDC GIS requires the knowledge of electric field distributions occurring in
the case of DC application. Starting from a capacitive field distribution at the moment of …
