Description / Abstract:
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.
