PMI’s Power Quality recorders are capable of recording myriad different measurements, though sometimes at a minimal cost of storage. While PMI’s recorders have industry leading storage capacity (and unlimited storage for PQ Canvass), sometimes it is necessary to record the absolute bare minimum in order to extend the duration of a recording.

This white paper walks the reader through a method to take basic core PQ measurements and derive several other measurements (such as 60Hz power, Voltage and Current THD, distortion power factor, voltage and current unbalance and even symmetrical components).
