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.…
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…
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…
Visualizing Loose Neutrals with RMS Capture Graphs
Loose neutrals represent one of the most hazardous and subtle single-phase service issues encountered by utility power quality (PQ) engineers. The condition arises when the neutral conductor connecting the center…
Analysis of Capacitor Bank Operation in Waveform Files
Electric utilities use capacitor banks to control power factor and regulate voltage on distribution systems. This paper describes a three-part method to recognize capacitor bank switch events within a power…
Voltage Regulation: Standards-based Compliance
Voltage regulation—the ability to maintain steady‑state RMS voltage within acceptable bounds—affects equipment performance, protection, and customer experience. Distributed energy resources (DER) add complexity via bidirectional power flow and daytime voltage…
Voltage Unbalance Within PQ Canvass Compliance Reports
Power Monitors, Inc.'s PQ Canvass is a secure, cloud-based platform built for power-quality (PQ) analysis. PQ Canvass has a beta feature of automated "compliance reports" that transform data uploaded from…
Streamlined PQ Analysis with the Latest PMI View Updates
