The development of HVDC networks leads to an increasing need of Gas Insulating Substations (HVDC-GIS). When an insulator is subjected to high thermoelectric dc DC stress, space charge accumulation can induce local increases of the electric field, which must be known and taken into account for the equipment design when the fields exceed several kV/mm.
