Summary:Short-circuit testing facilities are discussed for SF6 gas-insulated switchgear (GIS) equipment. It is shown that the supply voltage of 28kV will suffice to supply short-circuit current up to 80kA without severe distortions for four breaks used in the full voltage test of a tank-type SF6 gas circuit breaker (GCB). A new testing method using two transformers is proposed for a three-phase-in-one-tank-type GCB.
