Appendix P.1 Analogue Points to Monitor and Set Pick-up Thresholds for Overcurrent Protection

New SCADA Analogue input and control points have been made available to allow users to view and alter pick-up thresholds remotely (via SCADA) for both the Active Forward and Reverse Phase, Earth, SEF, and NPS elements. In addition, a further Analogue input and control point is provided for the Active Broken Conductor Pick-up threshold (ratio of I_nps/I_pps).

NOTE: The table below outlines the database points available Protection State Analogues and Protection Analog Controls features. For more details refer the N00-331 Database.
