PG&E and the New Breaker SF6 Leak Study - epa.gov

2008-3-25 · If the density monitor alarm set point drop is changed to 5 psi, and the same inputs used, this correlates to approximately a 5% decrease in SF6 mass from the original charge at 80 psig. Likewise, a 10% reduction in density equates to a 10% loss in SF6, as does a 5% reduction in density equate to a 5% loss in SF6.
