Sulfur Hexafluoride (sf6 gas) In Transmission and Distribution

Emission Reductions (continued) •During 2004 APS reported a SF. 6. Leak rate of 7.6% (13,236 lbs of SF. 6. emitted). This was accomplished by repairing or replacing seven of the Top 25 SF. 6. leaking breakers which potentially eliminated nearly 5000 pounds of SF. 6. emissions. • Additionally, this eliminated 70 maintenance work orders and SF. 6Get price
