Distribution Substation and Feeder Protection Course

Description

This course covers protection and control principles of utility distribution substations and feeder protection which includes fuses, intelligent electronic devices (IEDs) relays, and old-school time-overcurrent relays.

Feeder relays and apparatus are examined including reclosers. Power transformer protection is reviewed and it includes the cases of (1) currents mismatch caused by difference in current transformer (CT) ratios; (2) Delta-Wye transformation and currents shifts; (3) Mismatch induced by Load Tap-Changers; (4) CT saturation and remanence and (5) Inrush phenomena and harmonic content problems.
