Distribution Station & Feeder Protection

Distribution Station & Feeder Protection

This course covers utility distribution stations and feeder protection including fuses, new IED relays, and old school time overcurrent relays. Feeder relays and apparatus are examined including reclosers. Power transformer protection is reviewed including Current Mismatch Caused by Differing CT Ratios; Delta-Wye Transformation & Currents Shifts; Mismatch Induced by Load Tap-Changers; CT Saturation and Remanence and Inrush Phenomena and Harmonic Content problems.

Fuses, Relays, Reclosers, Surge Protection Devices
