The problem is that in most cases these pre-defined time intervals are based on some previous experience or empirical knowledge and rarely on scientifically sound data. Since the verification itself is a costly procedure it would be advantageous to put more effort into defining the required verification periods. Therefore, a fixed verification interval, recommended by various internal documents, standardised evaluation procedures and national legislation, could be technically and scientifically more justified and consequently more appropriate and trustworthy for the end user. This paper describes an experiment to determine the effect of alternating temperature and humidity and constant high current on a smart electronic electricity meter’s measurement accuracy. Based on an analysis of these effects it is proposed that the current fixed verification interval could be revised, taking into account also different climatic influence. The findings of this work could influence a new standardized procedure in respect of a meter’s verification interval.}, type={Artykuły / Articles}, title={Effect of environmental and operating conditions on the verification interval for smart electronic electricity meters}, URL={http://journals.pan.pl/Content/110241/PDF/art_15.pdf}, doi={10.24425/mms.2019.126328}, keywords={smart meter, verification interval, measurement accuracy, measurement error, accelerated aging}, }
