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.

Learning Objectives:

• Protection & control principles of distribution stations and feeders
• Transformer Differential Protection is studied along with overcurrent protection
• System Faults; station configuration & elements
• Differential Protection
• CT Saturation & Mal-operation of Transformer Protection
• CT Saturation & Restraint Differential Protection
• Fuses
• The Modern IED Relays (Intelligent Electronic Device).
