IEEE Draft Guide for Sulphur Hexafluoride (SF6) Gas Handling for High Voltage (over 1000Vac)Equipment

Abstract

This guide describes significant aspects of handling SF6 gas used in electric power equipment such as gas recovery, reclamation, recycling in order to keep the gas permanently in a closed cycle and avoiding any deliberate release in environment. The purpose is to provide stateof- 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 re-commissioning, topping up, refilling, checking the gas quality at site, sampling and shipment for off-site gas analysis, 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 Customised "Practical SF6 Handling Instructions", August 2005 edition, which was developed by the Study Committee B3, Task Force B3.02.01.
