Three abnormal situations leading to an uncontrolled release

Abnormal leakage. The method of risk assessment is similar to that used in section “leakage from sf6 gas – 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.
