Abstract:
Coil-based actuators for use in opening and closing the separable contacts of circuit interrupters provide increased initial velocity for opening strokes and damping at the end of opening strokes. Electronics for adjusting the current profile of current supplied to coil-based actuators additionally provide increased initial velocity for opening strokes and damping at the conclusion of opening strokes.
