Grounding switch for isolated phase bus

WebDisconnecting switches/grounding switches (1) Size and weight reductions were accomplished by using three-position switch blade systems for 168/204 kV or less three-phase common-type GIS and linear systems for 220 kV or larger isolated-phase type. (2) Operating mechanisms are fully automated. WebAug 15, 2024 · The grounding switch operates to provide a deliberate ground fault on one phase of the high-voltage bus supplying the power transformer, disrupting the normally balanced 120° phase shifted three-phase system by effectively removing one phase and causing the other two phases to become 180º phase shifted relative to each other.
