AB This paper presents a new qualitative method forassessing the power quality (PQ) of electrical systems using bothtime domain traditional indices and higher-order statistics. Themethod employs engineering data analysis (EDA) tools toanalyse and interpret the PQ data coming from real datasets.Boxplot of each index are considered an essential tool thatdeserves to be included and studied when an external dataset it isanalysed. But this research intends to go a step further, and forthis reason a new tool for the spatial visualization of supplyquality based on a radar chart is proposed.Each of its vertices constitutes an index, integrating from 3rd to6th order statistics with the traditional indicators SNR, SINADand crest factor. The proposed methodology is applied to theanalysis of real available signals and both, boxplot and radarchart, results are compared and commented. Finally, relationshipsare established between the altered indicators and the type(s) ofevent found in the signal.
