Overview 1.1 Scope This guide describes significant aspects of handling SF6gas used in electric power equipment, such as gas recovery, reclamation, and recycling, in order to keep the gas permanently in a closed cycle and to avoid any deliberate release into the environment. 1.2 Pur
39、pose To provide state-of-the-art technologies and procedures to minimize SF6gas emission to a minimum functional level for the electric power equipment to preserve the environment. This guide will include all the aspects for consideration during commissioning and recommissioning, topping up, refilli
40、ng, checking the gas quality at site, sampling and shipment for off-site gas analysis, and recovering and reclaiming during normal operation and at the end of the life of power equipment while dismantling. This guide also presents the state-of-the art tools and measuring devices including the necess
41、ary personnel protective equipment.

It is an inert gas with very low solubility in water and therefore presents no danger to surface water, ground water, or the soil. SF6has no impact on t

It is also a persistent greenhouse gas with an atmospheric life time (ALT) of 650 to 3200 years. The difference in the figures is a consequenc

49、one is not adequate to measure the environmental impact of electric power equipment based on SF6technology. The environmental impact of any specific application should be evaluated and/or compared using the life-cycle assessment (LCA) approach, as regulated by ISO 14040. SF6has to be used in a closed cycle. When gas removal from containment is needed, a proper handling procedure should be implemented to avoid any deliberate release into the atmosphere.
