With the emergence of renewable energy, new technologies for energy distribution across long distances, such as High Voltage Direct Current in Gas Insulated Substations (HVDC GIS) are developed. Under HVDC, the electric field distribution is not anymore determined by permittivity of materials but by resistivities and charge accumulation. In presence of gas/solid interfaces, the role of the surrounding gas on charge accumulation must be considered. In this work, we first present characterization methods which allow measuring the current passing through gas and solid insulators for different environmental conditions. Using these methods, we investigate the influence of several parameters (temperature, electric field, relative humidity) on the...
