The knowledge power quality levels, through objective approach, is based on the accumulation as measurement information. For a more complete characterization of power quality parameters it is necessary that the measurement process to include in the set of specific operations and evaluation of measurement uncertainty. Measurement uncertainty is a specific parameter of measurement method and conditions under which measurements are made. By this way, IEC 61000-4 series regulations "Electromagnetic compatibility" include a number of clarifications concerning the purpose of determinations, the level of accuracy and the level of uncertainty to be measured power quality parameters. The issue of evaluation of measurement uncertainty of power quality parameters, is presented in this article as a methodology, exemplified experimentally by measuring the nominal voltage supply, dips and swell in power distribution networks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
