Design of a measurement program to characterize distribution system power quality

The authors describe the design of a sampling and measurement program (sponsored by the Electric Power Research Institute, RP3098-1) to characterize distribution power supply quality in the United States. The program involves placing 300 monitors on sites in 25 utilities over a 2 year period. Power quality is measured in terms of frequency, magnitude and other characteristics of deviation from continuous supply of sinusoidal waveform power
