Three abnormal situations leading to an uncontrolled release

Abnormal leakage. The method of risk assessment is similar to that used in section “leakage from Sulfr hexafluoride – 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.

Myth About Sulfr hexafluoride Gas In Electrical Equipment

Apr 12, 2021 · How much gaz sf6 (quantified in kg) can escape due to “normal” leakage? This depends on the filling quantity, which depends on the rating and design of the equipment (volume and pressure). For HV switchgear the emission factor ranges from about 0.1% per year to 0,5% (0,5% per year is the maximum acceptable leakage rate according to IEC 62271-203)
