PDH UNITS: 4

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. Duration: 3hr 52min of video content Prerequisites: A solid background in electrical circuitry.
