  • FirstPower Group LLC wins Bid to Test SF6 Circuit

    SF6 gas is harmless to the environment, but leakage can cause operational problems for breakers that use SF6. The gas creates an airless environment within the circuit breaker that extinguishes the arc of the high voltage circuit. FirstPower Group LLC has been sampling, testing and correcting deficient SF6 breakers since 1995.
