Distribution customer power quality experience

A proactive approach to determining power quality by monitoring voltage disturbances and harmonic levels dictated by a power quality survey program is discussed. The authors present and discuss in detail some of the key objectives of the power quality program. A methodology for quantifying power quality as experienced by customers in a graphical form is presented. Several detailed case studies are presented to illustrate the methodology. Estimating algorithms for the duration and magnitude of the various types of power supply disturbances are developed and illustrated.<
