Electric Circuits 4 The fact that a three‚Äźphase circuit can have one of two phase sequences must be taken into account whenever two such circuits operate in parallel. The circuits can operate in parallel only if they have the same phase sequence.

BALANCED THREE-PHASE CIRCUITS The voltages in the three-phase power system are produced by a synchronous generator (Chapter 4). In a balanced system, each of the three instantaneous voltages have equal amplitudes but are separated from the other voltages by a phase angle of 120o.

Balanced Three-Phase Circuits The voltages in the three-phase power system are produced by a synchronous generator. In a balanced system, each of the three instantaneous voltages have equal amplitudes but are separated from the other voltages by a phase angle of 120. The three voltages (or phases) are typically labeled a, b and c.

tory treatment, we can justify considering only balanced circuits. The analysis of unbalanced three-phase circuits, which you will encounter if you study electric power in later courses, relies heav­ ily on an understanding of balanced circuits. The basic structure of a three-phase system consists of volt­

unbalanced circuits a greater understanding of the subject is required. For a variety of reasons it often becomes necessary to calculate the currents in both balanced and unbalanced three phase circuits. For example, the magnitude of the currents may be needed to properly size conductors,

An unbalanced system is analysed as the superposition of three balanced systems, each with the positive, negative or zero sequence of balanced voltages. When specifying wiring sizes in a three-phase system, we only need to know the magnitude of the phase and neutral currents.

designed to operate in the balanced state. Thus, in this introduc- tory treatment, we can justify considering only balanced circuits. Generating, transmitting, distributing, and using large blocks of electric power is accomplished with three-phase circuits. The

Referred to as a-phase, b-phase and c-phase. Two Types of Phase Sequences abc (positive) phase sequence Phase b lags a by 120° and c leads a by 120°
