A solid background in electrical circuitry is required to gain the most out of this course as it deals with the protection and control principles of distribution stations and feeders. Transformer Differential Protection; System Faults; Differential Protection; CT Saturation and Mal-operation of Transformer 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 and Currents Shifts; Mismatch Induced by Load Tap-Changers; CT Saturation and Remanence and Inrush Phenomena and Harmonic Content problems.
