Instrumentation, measurement techniques and analytical tools in power quality studies

The proper choice of instrumentation, measurement techniques and analytical tools is vital to the successful implementation of any industrial distribution system power quality study. Whether the desired result is the determination of harmonic distortion levels, a harmonic filter design, or transient waveform analysis, the proper choice of instrument, measurement technique and analytical tools can make the difference between a well engineered solution to a complex problem and an expensive failure. This paper reviews the points of consideration for power quality instrumentation, a description of appropriate measurement techniques, and a discussion of analytical methods.
