Temperature Rise Comparison of Switchgear in gaz sf6 2 and Air

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