sf6 gas-policy development in the Netherlands

As shown in this paper the Netherlands tries to develop a balanced policy for ncgg’s in close co-operation with industry. With its active approach the Netherlands policy strives for the use of switchgear that reduces overall greenhouse gas emissions. This will include insulating gas-insulated switchgear for the foreseeable future.

Spacer flashover in Gas Insulated Switchgear (GIS) with humid

Mar 01, 2020 · A laboratory setup has been constructed in the High Voltage Laboratory in TU Delft, the Netherlands, to find the influence of humidity on the flashover of a spacer. The model consists of a cast epoxy-resin sample and SF 6 resembling the insulation system of a GIS. The controlled parameters in the tests are the humidity-content and the gas pressure, while the temperature is kept constant at 20 °C, which represents the possible lowest temperature in the tropics.
