ABB_RSYN_25
Synchronism and energising check giving a close permissive from voltage, slip and angle windows, with breaker closing-time angle compensation and a continuous in-window confirm time.
When to use it
Use ABB_RSYN_25 when a breaker can close between two independently energised systems — a bus coupler, a generator incomer, a ring main, an interconnector — and closing out of synchronism would impose a damaging shock on the machines and the switchgear.
