Power quality monitoring is the process of “Acquiring, Analyzing, and Interpreting Measurement Data to Offer Practical Business Insights”. Voltage and current are continuously tracked by monitoring systems, which then analyze and interpret raw data using intelligent algorithms with little to no human involvement.

It is performed to “Ascertain the Root Cause and Extent” of the power quality issue, dips and swells, voltage transients, power interruptions, harmonics, and voltage unbalance can all be tracked, analyzed, and compared to equipment operation histories.
