Energy Quality in Voltage, Current and Power Signals

Abstract. This article deals with the processing of electrical signals for use in the analysis of the quality of electrical energy in installations. The calculations are based on a three-phase wave, taking into account the evolution in time of the sequential components. The currents within the system are also factored in, and one of the diverse theories of power in non-sinusoidal regimes is applied. As a result of the described processing, it was possible to show that the three-phase wave enables a better level of compression of the physical phenomena causing perturbations. Future studies will focus on quality parameters of electrical current signals, as these provide information regarding charge problems. The measurement of power brings a new focus, which allows the evaluation of perturbations according to their energy efficiency
