This course dives deep into the principles and practices of modeling and calculating balanced faults in electrical power systems. Participants will learn about various modeling techniques including omic, percentage, and per-unit models, and understand how to create and interpret one-line diagrams. The course covers essential concepts such as base value calculations, impedance diagrams, and the application of these models in real-world scenarios. Through detailed explanations and practical exercises, learners will develop the skills necessary to perform accurate fault calculations and enhance system reliability.
