With the power quality analyzers (as pictured below) that we have available, it is possible to analyze the quality of
electrical supply, as well as determine the effect of harmonics, transients, and flicker on entire buildings and sub
circuits. This is very important as far as control gear on fluorescent lights and electronic equipment are concerned.
 

Electrical utilities are working harder than ever to stay competitive, manage capacity and protect revenue. To
differentiate themselves from competitors, many utilities are offering power quality and other efficiency-related
services. As a result, new power quality measurement tools are reflecting this same multi-purpose field service ethic.
 

The three-phase analysers that technicians already use to measure power factor and trend power quality now offer
user-defined ratios for displaying readings as if measuring at the primary side of PT’s and CT’s. They also verify
revenue meters.
