AB This paper presents a proof-of-concept of a versatile Power Quality (PQ) analyserfor tracking the voltage supply in industrial and residential sectors. It implements 2DHigher-Order Statistics (HOS) to assess voltage quality, based more on the sinusoidal waveform than on power fluctuations. Beyond the second-order parameters and permissibledeviations regulated by the norm, EN 50160, the two-dimensional traces and probabilitydensity functions, along with a previously studied differential index, manage to identifydifferent states of the electrical grid. Waveforms were measured in the wall plugs of a publicbuilding. In regard to analysing reliability and voltage waveform, the results corroboratethat incorporating skewness and kurtosis indicators improves the characterisation, as wellas extracting the customers’ supply behaviour under normal and anomalous operations.The instrument showed good behaviour in site characterisation, and the implementedmethod was considered as a probabilistic approach for the risk assessment of an installation. The prototype was tested in the facilities of a public building of the university, beingable to detect deviations in 10 s traces of 3.9% in variance and 0.6% in kurtosis.
