Recognizing Transformer Energization in Power Quality Data
Transformer energization events occur frequently in electrical distribution systems and often appear in power quality recordings. These events can produce large transient currents and waveform distortions that may initially resemble…
Datacenter Power IV
High-speed protective devices in modern datacenters, such as low-voltage circuit breakers with electronic trip units (ETUs) offering instantaneous or short-time protection, are documented to operate in cases where standard Power…
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…
Merlin™ Chat in PQ Canvass
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…
Using PMI’s TLAR and TLAR-S Clamp-Style Current Transformers
Clamp-Style Current Transformers (CTs) are a convenient and safe way to measure current flowing through a conductor. PMI offers the TLAR line of iron core CT clamps in both the…
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.…
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…
