System to achieve high-speed directional and distance protection and for complete control of a two-breaker cell.<\/p><p style=\"font-weight: 400;\">Protect any transmission line with a five-zone combination of directional overcurrent elements and phase and ground distance elements. A graphical user interface system provides logic and application templates for standard line protection systems. Patented capacitor-coupled voltage transformer (CVT) transient overshoot logic enhances the safety of Zone 1 distance elements. Best Choice Ground Directional Element logic optimizes directional element performance and eliminates numerous directional adjustments. Optional supplemental logic prevents Zone 1 overshoots on series-compensated lines. Optional incremental components enable sub-cycle operation on critical lines requiring high-speed fault clearance.
