A three-phase power system is called balanced or symmetrical if the three-phase voltages and currents have the same amplitude and are phase shifted by 120° with respect to each other. If either or both of these conditions are not met, the system is called unbalanced or asymmetrical. In this text, it is implicitly assumed that the waveforms are sinusoidal and thus do not contain harmonics... For distribution net work, as consumers need, single phase supply only for lightning and apliences, supply company give them single phase connection,by equally distributing the load, on all three

- This chapter is an introduction to unbalanced three-phase power systems. It presents several practical examples of analysis applied to unbalanced three-phase systems and a number of observations are made based on the numerical examples.
- ADVE MUFAU FFE Eliminate Voltage Unbalance Voltage unbalance degrades the performance and shortens the life of a three-phase motor. Voltage unbalance at the motor terminals can cause current unbalance that is far out of proportion to the voltage unbalance. Unbalanced currents lead to torque pulsations, increased vibrations and mechanical stresses, increased losses resulting in lower …
