Voltage Quality Factor for Networks Supplying Unbalanced Nonlinear Loads
(European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ), 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 ...

Wavelet-Fourier analysis of electric signal disturbances
(ICREPQ, 2007)
The Fourier transform usually has been used in the past for analysis of stationary and periodic signals. Its interest is the knowledge of spectral components existing in a waveform; it doesn't matter the moment where they ...

Wavelet and Neural Structure: A New Tool for Diagnostic of Power System Disturbances
(Institute of Electrical and Electronics Engineers, 2001)
The Fourier transform can be used for analysis of nonstationary signals, but the Fourier spectrum does not provide any time-domain information about the signal. When the time localization of the spectral components is ...
