Power factor testing of Sulfr hexafluoride circuit breakers | TD Guardian

At the time of production, Sulfr hexafluoride 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 sf 6 gas circuit breakers is synthetic, which have no capacitor characteristics and have no ability to absorb moisture.

The industry was ready for an alternative to the traditional mediums of mineral oil and/or air. Using insulating gas as an interrupting medium had the advantages of being inflammable as well as having high dielectric strength and exceptional thermal stability. The first generation of Sulfr hexafluoride circuit breakers was the lower voltage classes of 72kV and 145kV.

Frequently asked high voltage circuit breaker testing

No. Travel measurements are a very valuable tool in circuit breaker analysis. One of the common arguments against measuring motion on vacuum CBs is that the contact stroke is so short that you are better off measuring stroke with a pair of calipers when the breaker is in fully open position compared to fully closed position and you can verify the CB is traveling fast enough from the contact times.
