Scope
"This guide describes significant aspects of handling SF6 gas 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. Purpose To provide state-of-the-art technologies and procedures to minimize SF6 gas 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@ refilling@ 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 necessary personnel protective equipment. The basis for the preparation of this guide is CIGRE Brochure No. 276@ Guide for preparation of customized ""Practical SF6 handling instructions@"" August 2005 edition@ developed by the Study Committee B3@ Task Force B3.02.01."
