This paper describes the methods for collecting, characterizing, and analyzing RMS voltage variation measurements during a distribution system power quality monitoring program. The measurements were collected from the primary distribution systems of 24 utilities in different geographic regions of the United States. The objectives for the site selection process are offered. The techniques for measurement triggering are explained. Novel techniques regarding the characterization of RMS voltage variation quantities by resolution into measurement components are described. The measurement, temporal and spatial aggregation of the components from a database at analysis time is presented. Key final results of RMS variation magnitude statistics are submitted.
