SMOR-B™ DDS Feeder Management System Protection and Control The SMOR-B, a digital feeder management system, provides feeder protection and control in one integrated package. Overcurrent Units Overcurrent elements include: s Phase and ground time delay s Hiset and loset phase and ground instantaneous s Negative sequence time delay Directional Units Time Synchronization Load Profile Recorder Synchronization can be controlled through the keypad, communication software or the IRIG-B input. The average and RMS current are calculated for a 15, 30 or 60 minute period for each phase. Event Recording...
