Abstract

This white paper provides an overview of the Event Capture function available with PMI power quality analyzers and introduces the Event Change Report, generated by Merlin™, PMI’s AI-powered analysis assistant. Event capture is a trigger-based recording function that captures power disturbances on a cycle-by-cycle basis, offering significant memory efficiency over continuous waveform recording. This paper covers what event capture is used for, how to configure it through PQ Canvass, and how Merlin™, PMI’s AI-powered analysis tool, transforms captured event data into actionable insights. Topics include threshold configuration, the Event Change Table Report, and the Event Change Report’s ten analysis sections covering severity assessment, compliance, pattern identification, attribution, and recommended next steps.
