sulfur hexafluoride analysis for 110kv

Sep 01, 2001Sulfur hexafluoride is an electronegative gas and therefore electrons released into it readily combine with SF molecules to form SF ions. The mobility of these ions is much lower than that of the free electrons. ... As an example we have analyzed a 110kV GIS barrier. ... The electric field analysis program uses an FEM model prepared by a CAD ...
