Figure 7.
The map shows the conductor passing through a conical spacer inside a cylindrical enclosure. The maximum electric field is 4.03 kilovolts per millimetre. The electric field scale ranges from 0 to 2.5 kilovolts per millimetre. Higher field intensity occurs along the conductor surface and around the junction between the conductor and spacer. Lower field intensity occupies most of the spacer and surrounding sulfur hexafluoride region.Electric field distribution in the HVDC GIL model assuming a constant electrical conductivity of the SF6 gas
