Abstract

Power quality investigations are often intricate, time consuming, and prone to oversight. Faced with a long duration recording, engineers must sort through an enormous volume of events, trends, and waveforms, and the sheer amount of information can make it difficult to decide where to begin or what to prioritize.

To address this challenge, Power Monitors, Inc. developed Merlin™—a Large Language Model–driven analysis tool built specifically for PMI power quality recorders. Merlin™ is designed to review all major elements of a PQ dataset and surface the most relevant issues, helping engineers move quickly from raw data to focused, actionable insight.

This white paper focuses specifically on how Merlin™ analyzes specific power quality focus areas and how those insights help guide a power quality engineer through their overall investigation.
