Abstract

The paper presents a prototype of cost-effective device mandated to identify, classify and measuring typical disturbances characterizing the quality of power supply systems. In particular, variations from the nominal root-mean-square value of the voltage signal, referred to as sag, interruption and swell, are taken into account. Moreover, specific functionalities implemented on the prototype offer the possibility of measuring the apparent and active absorbed by a connected load, as well as verifying voltage spectral purity by mean of the evaluation of a traditional total harmonic distortion index.
