Sf6 purity analyzers in switchgears - Switchgear Content

May 20, 2020 · gaz sf6 gas plays a key role in switchgears and the percentage of gas purity has a direct effect on the switching. Commercially, gaz sf6 is supplied in pressurized bottles or liquid tanks. The gas of these bottles has a minimum degree of purity of 99.9% and may possess the following impurities according to IEC 60376: carbon tetrafluoride (CF4) <0.03%

Power factor testing of high-voltage sf6 gas circuit breakers

At the time of production, insulating gas gas circuit breakers are subject to a high-voltage withstand test. This incorporates an AC High-Potential (Hi-Pot) test transformer capable of achieving the required high-voltage levels (per industry standards). Therefore, field Hi-Pot testing is also not necessary or required. The insulating material used in the manufacture of modern Sulfr hexafluoride gas circuit breakers is synthetic, which have no capacitor characteristics and have no ability to absorb moisture.

Myth About insulating gas Gas In Electrical Equipment

Where is sf6 gas used? The following applications are known. For some of these most probably you haven’t heard of. For sound insulation in windows, In vehicle tyres, Is gaz sf6 a health hazard? Pure sf6 gas is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is insulating gas harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. What is the overall contribution of insulating gas used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE). In an Ecofys study the contribution to the greenhouse effect in Europe is estimated to 0.05 % (*).

HV circuit breaker testing - Electrical test equipment

Most manufacturers don’t recommend Power Factor testing sf6 gas dead tank circuit breakers. To check the quality of the Sulfr hexafluoride gas i.e. the insulation of the CB, it is recommended to perform a moisture and purity test on the sf6 gas gas. There have been some reports that you can determine some issues within the CB contacts with a Power Factor test, so several utilities still promote and perform these tests on Sulfr hexafluoride circuit breakers.
