SF6 Gas Handling
• SF6 gas is a potent greenhouse gas used in electric power systems and industries.
• Proper gas handling practices are crucial to minimize emissions.
• Pro tips include relieving pressure before disconnecting, following proper start-up procedures, preparing equipment, recovering gas on failed breaker, checking filters, testing SF6 cylinders, and using nitrogen to rinse the recovery system.
• If a breaker fails, a gas analysis should be performed and a small amount of SF6 gas recovered.
• Nitrogen can be used to rinse out internal components if a recovery system becomes contaminated with sulfur dioxide.
