  • Leak Testing High Voltage Switchgear - LACO Technologies

    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
