Sinusoidal Steady-State in Three-Phase Circuits
CHAPTER OBJECTIVES
-
To define and explain balanced and unbalanced three-phase systems and to extend the concepts of active power, reactive power and complex power to such systems.
-
To develop and employ relations between line and phase quantities in Y-connected and ∆-connected three-phase circuits.
-
To emphasise constraints on line quantities in three-phase three-wire and four-wire systems.
-
To develop a systematic procedure to analyse sinusoidal steady-state in three-phase balanced circuits using Y-equivalent and single-phase equivalent circuits.
-
To show how to use phasors, phasor equivalent circuits and phasor diagrams for solving three-phase circuits under sinusoidal steady-state condition. ...
