On the assessment of voltage unbalance
Proceedings of 14th International Conference on Harmonics and Quality of Power - ICHQP 2010, 2010The management of voltage unbalance in a power system is supported by the knowledge on the contribution of a single unbalanced load/source to the total level of voltage unbalance observed at a Point of Common Coupling (PCC) in an interconnected power system with unbalanced loads distributed all over.

The chapter deals with rotor mass unbalance fault. Diagnosis is done both using steady-state signal as well as starting current transients. Concordia is formed using steady-state current and analyzed. The Concordia -based assessment is done using starting current transients.

Unbalance effects in modulators
Journal of the British Institution of Radio Engineers, 1955The various groups of output frequency-components which can be produced in rectifier modulators of the shunt (or «Cowan») and ring types are separated into those which are inherent in the operation of the modulator and those which are absent when the modulator is perfectly balanced.

In this paper the effects of voltage unbalance in both the Complex Current Unbalance Factor (CCUF) and the Torque Ripple Factor (TRF) of a three-phase induction motor have been discussed. The effects of 13060 points of voltage unbalance taken around the limit of standards (VUF = 2%) have been analyzed, since the largest number of international ...
