Abstract: In recent years, the rapid growth in the importance of electrical power quality (PQ) has created a demand for highly effective monitoring instruments, able to evaluate different PQ parameters. Instrument suppliers propose for the PQ measuring systems a variety of sizes and configurations, owing to the growing application fields. The metrological characterisation of these instruments is a problem because they must satisfy different requirements. In this paper, we discuss about the characterisation of PQ analysers, starting from an overview of current main international standards. As a case study in the paper a testing procedure is proposed, reporting also the characterisation results obtained with a multifunction PQ analyser prototype.

Keywords: power quality analysis; power system transient; distortion; voltage measurement; signal analysis; characterisation; IEEE standards; IEC standards; electrical power; instrumentation.
