The basic alternating current circuit, the difference between single-phase and three-phase circuits, the components of impedance, Ohm’s Law, and symmetrical and asymmetrical currents. The module also provides an overview of a typical power distribution system and its components, and how power systems are represented schematically.
Course Code: EQ1
Runtime: 30 minutes
Explores the overhead distribution system, covering poles, insulators, conductors, connectors, guying and clearances, providing a foundation for a more in-depth discussion in the Sags and Tensions course.
