Power Quality Analysis is the first part of “Energized Electric Motor Testing.”   Power Quality issues first appeared with the advent of the vacuum tube. However, in the 1980’s personal computers, PLCs, VFDs, UPSs and electronic lighting, began appearing in increasing numbers. The effects of these discontinuous loads can have deleterious effects on motors and electrical / electronic equipment in general. In this topic we learn how to use your motor tester as a power quality analyzer, to identify numerous power quality anomalies that can substantially reduce your motor longevity.
