Voltage Quality Factor for Networks Supplying Unbalanced Nonlinear Loads [PDF]

, 2005
While the common term for describing the harmonic content and the unbalanced loading of the three-phase supply is power quality, it is actually the quality of the voltage that is being addressed in most cases. The power supply system can only control
