J.M. Sierra-Fernández, J.J. González De La Rosa, A. Agüera-Pérez, J.C. Palomares Salas, O. Florencias-



The present works deals with the presentation and test of a novel Power Quality index, based in Higher-Order cumulants. Synthetics are used for test different start point, amplitude and
length for the most common Power Grid disturbances (DIP,Oscillatory Transient, Harmonic Temporal Distortion and Impulsive Transient), obtaining a high accuracy (over 99% in some disturbances). Then real signals are used for confirm synthetics results. Finally, the Power Quality index presented, is confirmed with real signals as a good tool for detect imperfections in the power waveform.
