sf6 emissions testing for 132kv

Q: Can the circuit breaker interrupt if there is a leak and no sf 6 gas is available? A: Yes, the vacuum interrupters are independent of the sf6 gas gas and all the interruption occurs inside the vacuum interrupters. sf6-gas gas is only used for insulation.. Q: What is the probability of sf6 leakage? A: The low leakage rate is possible as the normal pressure is 1.5 bar (22 psig) or less, as the SF ...

    For example:- phase-to-ground clearance for 132 kV systems is around 1200 mm in air, compared to 80 mm in SF6 gas at 4.0 bar(g).This gives a direct reduction in dimensions of the high-voltage equipment by 15 times. Consequently, the size of SF6 insulated equipment is around 6% that of air insulated equipment for this voltage class (132kV).
