Performance analysis of high voltage SF6 circuit …

To study the insulation performance and the dielectric recovery characteristics based on the interaction of electric field and gas flow field in high voltage circuit breakers (HV CBs), a two-dimensional coupling physical-mathematical model has been developed. And the influence of shock wave and turbulent flow has been taken into consideration.

SF6 gas measuring devices – Synergy Power Systems

The IEC 60480 directive also stipulates the limit values for the re-use of SF6 gas. It is absolutely necessary to know the gas quality before carrying out maintenance works on a circuit breaker in order to be able to decide on preparation, re-use or disposal of the SF6 gas. The essential quality criteria for SF6 gas in circuit breakers are as

Premier Utility Services Launches Substation SF6 …

2012-8-10 · "This gas, known primarily for its insulation properties in utility substation circuit breakers, can leak at mechanical fittings and couplings. If too much SF6 gas leaks, a astrophic failure of the breaker can occur, costing over $100,000 to repair and resulting in localized outages," said Marc Makely, president of Premier.

Leak Detection - Transmission & Distribution Services

The new device that has proved very useful for detecting SF 6 leaks is the infrared laser-scanning unit. This detector scans the entire circuit breaker using a laser and detects the specific infrared signature of SF 6 gas. The SF 6 leak appears as black smoke on the video used to record the scan.
