  • SF6 gas measuring devices – Synergy Power Systems

    The SF6 gas must always be pure since humidity and toxic or corrosive decomposition products in circuit breakers impair the insulating properties of the gas. The gas quality has to be monitored in accordance with the F-gas Regulation (EU) 517/2014. The IEC 60480 directive also stipulates the limit values for the re-use of SF6 gas.
