Sulfr hexafluoride gas in medium-voltage switchgear | TD Guardian Articles

In this issue, we discuss the use of sf6 gas (sulfur hexafluoride) gas in medium-voltage switchgear. Sulfr hexafluoride has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses Sulfr hexafluoride gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.

The temperature can be controlled by maintaining the cooling system and regulating the load. Oxygen can be controlled by maintaining the oil preservation system. Assuming that the transformer insulation moisture level was 0.5% maximum as suggested by most manufacturers when it was installed, how can the insulation level increase over time?
