SF6 Decomposition monitoringsolutions for powergrid

SF6 Decomposition monitoringsolutions for powergrid

Measuring instruments are used to monitor ambient air, trace leaks and to measure the SF6 quality of electrical operating equipment. 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.
