This paper presents an alternative methodology for evaluating the functional perfomance of electric power quality measurement instruments, which is elaborated based on the results of the application in laboratory of three procedures found in documents that deal with this subject. It is a proposal which includes the metrological and technical aspects of each electric power quality parameters required by IEC 61000-4-30 through the use of ISO-GUM. From the implementation of this methodology, it is possible to identify the attributes and deficiencies of the instrument under evaluation and show them in a report that expresses its performance. Streszczenie. W artykule zaprezentowano metodologi˛e oceny metod pomiaru jako´sci energii. Uwzgl˛edniono parametry rekomendowane przez norm˛e IEC 61000-4-30 oraz zalecenia ISO-GUM. Metodologia pozwala na ocen˛e wad i zalet poszczególnych metod. (Metodologia oceny wła´sciwo´sci mierników jako´sci energii) Keywords: Power quality monitors, calibration, IEC 61000-4-30, error measurements Słowa kluczowe: Metodologia oceny wła´sciwo´sci mierników jako´sci energii Introduction The electricity sector has recently adopted a deverticalized model that imposes new rules in order to satisfy the final consumer. In this context, power quality (PQ) has become one of the most important questions to be addressed [1]. In general, PQ analysis is a way of assessing the continuity of supply and compliance with certain parameters related to the limits established in standards. For the assessment of PQ parameters, measuring campaigns have been developed and implemented worldwide by regulators, electric utilities and consumers [2, 3]. For this to be possible, it is necessary to provide the electrical network with specialized instruments. This demand has fostered the development and manufacture of many different electric meters that are available today in the market. However, it is noteworthy that the absence or neglect of[...]
