Merlin™ Chat is a conversational AI interface within PQ Canvass that allows engineers to ask natural-language questions about a power quality recording and receive detailed, technically grounded answers. Built on…
Modern Flicker Analysis Using PQ Canvass and Merlin™
Voltage flicker is one of the most common power quality complaints reported by utility customers. The term flicker refers to visible changes in lighting intensity caused by rapid fluctuations in…
Automated Stripchart Analysis With Merlin™
In power quality investigations, triggered waveforms often claim the spotlight, but it is the stripchart that tells the story of the entire recording. Reviewing this data manually is tedious, error-prone,…
Event Capture and Analysis with Merlin™
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.…
Power Quality Focus Areas with Merlin™
Introduction 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…
Detailed Waveform Analysis with Merlin
Power Quality investigations are frequently complex, difficult, tedious and error prone. When sitting down to analyze a long duration power quality recording as part of a critical investigation, the vast…
Merlin™: AI-Assisted Power Quality Analysis In PQ Canvass
Merlin™ is an AI-assisted analysis suite built for PQ Canvass. Instead of manually stepping through dozens of waveforms and days of trend data, Merlin™ reviews an entire recording and presents…
Meet Merlin™: How AI is Transforming PQ Analysis
As grid and load complexity increases and distributed generation proliferates, utilities face a torrent of sensor data that outpaces human capacity to interpret it. This paper introduces Merlin™, an analyst-grade…
Power Quality for the Non-PQ Professional
This paper provides a plain-language overview of power quality — what it is, why it matters, and what can be done to maintain it. It is written for professionals outside…
Defining and Measuring Rapid Voltage Change
Rapid Voltage Change (RVC) represents a specific category of power quality phenomena characterized by a fast transition in the RMS voltage between two steady-state conditions. Unlike a voltage dip or…
