Mar 04, 2019 · The current SF6 Regulation came into effect in 2011, setting an annual emission rate limit for SF6 as a percentage of a GIE owner's cumulative SF6 nameplate capacity. Allowable emission rates under the SF6 Regulation started at 10% in 2011, decreasing by 1% per year until 2020, after which point the allowable emission rate remains constant at 1%.

    Abnormal leakage. The method of risk assessment is similar to that used in section “leakage from SF6 – filled equipment” which deals with normal leakage. Internal fault. An internal fault can develop when an arc is formed abnormally between the main conductors of an item of switchgear, or between a main conductor and an earthed conducting part. External fire. Fires in outdoor installations rarely cause problems because of the relative absence of flammable material in the vicinity of the switchgear. People also search for
