Figure 9.
The upper panel presents the horizontal configuration and the lower panel presents the vertical configuration. Each panel shows a circular cross section of the conductor, spacer, and enclosure together with a corresponding three-dimensional view. The flow velocity scale ranges from 0 to 0.35 metres per second. Higher flow velocity occurs around the conductor surface and along the enclosure boundary. The horizontal configuration shows localised higher velocity regions around the conductor and outer enclosure. The vertical configuration shows a more uniform velocity distribution around the conductor with higher velocity concentrated close to the conductor surface. The x, y, and z axes indicate the orientation.Flow velocity of the SF6 gas in a horizontally and vertically arranged HVDC GIL
