PMI has introduced the Tensor, a next generation plugin power quality analyzer. The Tensor (Figure 1) is designed to plug in to any standard 3-prong receptacle. This white paper will…
Getting PQ Data from your SCADA System
DNP3 (Distributed Network Protocol) is a communication protocol used primarily in utilities and industrial settings for automation and control systems. It is designed to enable reliable, secure communication between control…
Using PQ Canvass
PQ Canvass is an advanced cloud-based software application that enhances power quality analysis. PQ Canvass revolutionizes power monitoring with its comprehensive browser-based functionality, eliminating the need for additional software, and…
Electric Vehicle Charging and Power Quality
Several months ago PMI purchased a Nissan Leaf all-electric vehicle. The Leaf has an approximate range of 90 miles which fits well with our day to day usage for local…
Revolution Download in PQ Canvass
Revolution meters are compact, cellular-connected power monitors. Unlike the Tensor, Seeker, Guardian, and Bolt devices, which initiate their own uploads to PQ Canvass, Revolutions do not push their recordings to…
PQ Canvass API Access
Introduction Electric utilities rely on power quality monitoring to maintain grid reliability, meet regulatory requirements, and respond to disturbances across their distribution networks. As monitoring deployments grow — spanning substations,…
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…
Power Analysis with Distorted Waveforms
Many power quality engineers are familiar with the concepts related to the power triangle such as real power, reactive power, apparent power and power factor. The construction of the power…
Why Notching Disrupts Power Quality and How To Stop It
Wave notching is a type of voltage distortion that appears as a very fast, repetitive dip or "notch" in the sinusoidal waveform of an AC power system. This periodic disturbance…
Windows PMI View Introduction
Introduction Power Monitors’ Windows PMI View is a desktop app for Windows 10/11 that lets you manage your Power Monitors’ recording devices. The application seamlessly connects to PMI recorders, providing…
60Hz Phasors and Extended PQ Measurements
This white paper walks the reader through a method to take basic core PQ measurements and derive several other measurements (such as 60Hz power, Voltage and Current THD, distortion power…
