Three-phase AC

Power systems are almost universally three-phase AC. This gives a significant saving in the construction of all power system equipment from generators to transmission lines and con­sumer equipment compared to single – phase [ 1] . Even more importantly, three-phase very elegantly provides the rotating magnetic field required in synchronous and induction genera­tors, as described […]

Effects of Reactive Power Flow – Power Factor Correction

Figure A.21 represents a basic circuit of energy transportation from a generator to a consumer through a transmission line, which is simply represented by a series inductance and resistance. The consumer is represented by an inductive resistive impedance. The reason for these rep­resentations are explained in Chapter 5. The consumer ‘absorbs’ both PL and QL. […]
