sf6 check for leaks for gis

SF 6 is always used in gas tight compartments, which greatly minimise leaks. As the quantities that leak from the switchgear are low, the contribution to the greenhouse effect can be considered extremely minimal to affect climate changes. Nevertheless, there are toxic by-products that are produced in SF 6 during arcing.
