Overhead and underground transmission, conductors, towers, insulators, shield wires, HVDC, and FACTS devices — how bulk power actually moves from generation to the distribution system, and the reactive-power physics that governs it.
This module covers the bulk transmission tier — 69kV through 765kV and beyond — where a line's own distributed capacitance and inductance start behaving like a system component in their own right. You'll work through conductor selection and sag-tension physics, the insulation-coordination logic behind towers and insulators, why underground transmission is the exception rather than the rule, when HVDC beats staying AC, and how utilities hold voltage steady on lines long enough for the Ferranti effect to matter.
By the end of this module you should be able to explain why a lightly loaded EHV line can raise its own receiving-end voltage above the sending end, and why an SVC, a STATCOM, and a switched capacitor bank are three different answers to what looks like the same reactive-power problem.
