Figure 8.
The left panel corresponds to 2 per cent relative humidity and records a maximum electric field of 3.88 kilovolts per millimetre. The right panel corresponds to 30 per cent relative humidity and records a maximum electric field of 2.51 kilovolts per millimetre. Both panels show the conductor passing through a conical spacer inside a cylindrical enclosure. The electric field scale ranges from 0 to 2.5 kilovolts per millimetre. Higher field intensity concentrates along the conductor surface and near the spacer junction, while lower field intensity occupies the surrounding sulfur hexafluoride region.Electric field distribution in the HVDC GIL model with the application of (12) in the gaseous domain (left: gas humidity content RH = 2%, right: gas humidity content RH = 30%)
