High voltage DC circuit breaker HVDC circuit breakers are difficult to build because of arcing : under AC the voltage inverts, and in doing so crosses zero volts, dozens of times a second. An AC arc will "self extinguish" at one of these zero crossing points, because there cannot be an arc where there is no potential difference.

The use of an SF6 camera is arguably the best method of finding leaks. A camera such as the FLIR GF306 has the potential to pinpoint very small leaks (up to 0.5lb SF6 annually). The great thing about using a camera is that there is no guess work – just point it at an area where you believe there to be a leak and let the camera record the observations.

2017/8/243. Is SF6 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. However in electrical switchgear the SF6 gas is always used in gas tight compartments, greatly minimising leakage.
