Лекция 060-1. Трехфазные электрические цепи. Основные понятия

This lecture reviews the key concepts of three‑phase electrical circuits, beginning with a recap of the previous session. It discusses the advantages of using three‑phase systems, offers a brief historical background, and explains the fundamental elements of a three‑phase system, including the generator and consumer subsystems. The talk also covers possible connection schemes between generators and consumers, and examines line and phase voltages and currents in three‑phase networks. Finally, it highlights topics often omitted in textbooks and concludes with a summary of the main points.
