The surface charge accumulation is very likely to trigger the surface flashover, which limits
the large-scale application of DC GIL/GIS. This article comprehensively reviews the effect of …

Recently it was shown that it is possible to predict the breakdown voltages of arbitrary
electrode configurations under standard voltage applications for electron attaching gases …

In this study, experiments were performed to measure the inception and breakdown voltages
of SF6/CO2 mixed gases with varying mixing ratios at two different pressures (1 and 2 bar) …

SF 6 has for decades been widely used in high voltage insulation and switching
applications, eg in gas insulated switchgear. Despite its widespread use some important …

In this contribution, a new procedure to systematically identify and quantify novel molecular
gases with low global warming potential for application in high voltage insulation as gas …

To reveal the decomposition mechanism of SF 6 under negative DC partial discharge (PD),
a PD hybrid numerical model of SF 6 was constructed based on fluid dynamics and plasma …

The breakdown electric field strength in synthetic air, CO 2, a mixture of CO 2 and O 2, and
CF 4 was investigated under conditions relevant for high voltage insulation systems …

Owing to the strong penetration ability of X-rays and the imaging visibility, X-ray inspection
has been gradually applied to power grids. However, various problems occur in the …

Charge generation at the interfaces of gas-insulated switchgear or gas-insulated lines is
mostly studied from a macroscopic point of view. Integral current measurements are a …

The focus of this paper is on the effectiveness of lightning impulse (LI) with different
parameters for detecting protrusion defects in gas insulated switchgear (GIS). The study …
