The quality of the SF 6 gas must be analysed, since it can lead to chemical reactions in the gas when used in gas-insulated switchgear, due to the high energy occurring there. An analysis of the SF 6 gas quality is always recommended and should be an integral part of the maintenance strategy, especially before any gas handling.SF6 gas solutions - WIKA

SF 6 is a non-toxic, inert insulating and quenching gas of high dielectric strength and thermal stability. Thus, it is used in enclosed medium and high voltage switchgear as an arc quenching and insulating gas due to its properties. Unfortunately, the same properties that make SF 6 an excellent insulating gas for GIE also make it a potent greenhouse gas.SF6 Circuit Breaker Types, Working Principles Maintenance.

Load and Number of Switching CyclesProspective Service LifeMechanical Life SpanElectrical Life SpanAssessment of The ContactsThe life span of switchgear basically depends on the size of the load and the number of switching cycles. Instead of a time span, with electromechanical switchgear reference is usually made to the number of operations, as the ageing mainly depends on the stress during switching and less on the on- and off-phases between. The maximum number of operations is determined by the wear of heavily loaded components in: 1. Contactors, 2…See more on electrical-engineering-portal.com[PDF]Hidden Risks of Aging Electrical Systems
