This course deals with three-phase AC systems, the mainstay of industrial power supplies and certain types of electrical machines. The associated three-phase loads, whether symmetrical or asymmetrical, will be studied, along with the resulting active, reactive and apparent powers. Reactive power compensation methods will be developed.
This course also deals with transient regimes, induced by the switching on, switching off or failure of circuits on their source, whether DC or AC. The importance of studying transients lies in the fact that they are the basis for the operation of devices found in many modern applications such as power distribution, electric drives, battery charging, switch-mode power supplies and lighting.
