sf6 Transfer for Maintenance

2021-3-15The procedures for handling nonfaulted SF6 are well covered in manufacturers' instruction books. These procedures normally consist of removing the SF6 fromthe circuit breaker, filtering and storing it in a gas cart as a liquid, and transferring it back to the circuit breaker after the circuit breaker maintenance has been performed.
