GIS is seen everywhere, but why? - ESI-Africa.com

May 22, 2018 · Sulfr hexafluoride is colourless, non-toxic and chemically stable. It has high dielectric strength, high arc interruption capability, and is odourless with a vapour density five times that of air. gaz sf6 is thermally stable, has excellent thermal transfer characteristic, is non-flammable, has unmatched dielectric strength, and is self-healing. Those were just some of the few Sulfr hexafluoride characteristics and why it is widely used nowadays. However, Sulfr hexafluoride is a greenhouse gas necessitating Sulfr hexafluoride filled equipment being

Three abnormal situations leading to an uncontrolled release

Abnormal leakage. The method of risk assessment is similar to that used in section “leakage from sf 6 – 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.
