SF6 Circuit Breaker Repair Procedure: Infrared SF6 Leak Detection. Typical SF6 Gas Circuit Breaker Leak Repairs. SF6 circuit breaker leaks typically occur between the porcelain and base mounting flange or at bushing end cap locations. Click the links below for details on how TDS technicians can reliably repair these leaks with custom designed clamps and our rubber-based, non-adhering leak sealant. SF6

Leak rate thresholds, or rejection limits vary from approximately 1 x 10^-4 to less than 1 x 10^-5 atmcc/sec SF6, and depend on breaker design, size, and other factors. Several leak testing methods can be employed on the production floor to accomplish the goal of providing a leak tight product to the end user. Leak testing not only identifies and pinpoints unacceptable leaks (so they can be repaired), but

−Pass/Fail Leak Rate: Acceptable SF6 gas loss rate is any rate less than 0.5% of the initial breaker SF6 gas content per year. •A new 72kV breaker contains 29 lbs. of SF6 @ 67 psi pressure. −0.5% of 29 lbs. = 0.145 lbs. per year (10,730 cm3per year). −Adjusted Rate for Testing =.0204 cm3per minute.
