What are the reasons that affect the accuracy of sulfur hexafluoride gas humidity detection?The level of SF6 gas humidity has a great impact on the arc extinguishing performance,insulation strength and life of electrical equipment,so the accuracy of SF6 gas humidity detection results is particularly important.

　　Therefore,Fillier analyzed the reasons why the ambient temperature affected the detection accuracy of SF6 gas humidity.Through the experiment,it is found that the humidity measurement result of sulfur hexafluoride gas increases with the increase of temperature.

　　Thus,the curve cluster graph of sulfur hexafluoride gas humidity affected by operating ambient temperature was established,which solved the problem that the test value could not be compared with the standard value due to the difference between the test temperature and the standard temperature(20℃).

　　At the same time,it is pointed out that the vapor of hydrocarbon impurities in sulfur hexafluoride detected in Liming will also affect the accuracy of humidity detection results when the ambient humidity is high or when the***instrument is used.For more information,call 139-4929-0069.
