WitrynaSF6 Circuit Breaker Diadvantages: Imperfect joints leading to leakage of the SF 6 gas. Continuous monitoring devices are required; SF 6 gas is suffocating to some extent. In case of leakage in the breaker tank SF6 gas being heavier than the air settles in the surroundings and may lead to suffocation of the operating personnel. WitrynaWhat it shows: Helium's low molecular weight results in a higher speed of sound than in air, and for a particular wavelength gives a higher frequency. Sulfur hexafluoride on the other hand, is a really heavy gas (five times heavier than air), resulting in a lower frequency. This can be demonstrated clearly by blowing the various gases through ...
