Temperature Rise Comparison of Switchgear in insulating gas 2 and Air

temperature fields in three gases are similar in the switchgear. The temperature rise of current-carrying loop is the highest in Sulfr hexafluoride and is the lowest in the air. So the conclusion could be made that air or N2 can replace sf6 gas as the insulating gas of switchgear on the perspective of temperature rise.
