Understanding Harmonic Power
Harmonic power is a complex and often misunderstood topic. This leads to misinterpretations, including using a harmonic power analysis when the measurements aren't physically meaningful. An overview of harmonic power…
An Overview of IEEE 1250 – Guide for Identifying and Improving Voltage Quality in Power Systems
The IEEE 1250 standard was developed in response to the introduction of modern electronics onto an older electrical grid. These newer electronics were not necessarily built to withstand the traditional…
Skin and Proximity Effect on Power Transmission
This paper describes what skin effect and proximity effect are, how they influence electric power transmission, and what steps are taken to reduce their losses.
Getting Started with Harmonics
Harmonic distortion has become an increasingly important subject for large power consumers. Non-linear loads continue to be adopted into customer systems, which often are the root cause of power quality…
Live PQ Waveforms in a Web Browser
PQ Canvass is the next generation of online power quality analysis tools provided by PMI. This new cloud service offers enhanced graphing, a full suite of PQ analysis tools, recording-based…
Merging Recordings in ProVision
Many PQ investigations end with a follow-up recording to verify a problem has been corrected and to gather a baseline for any further issues. Analyzing the “before” and “after” recordings…
Separating Voltage Sags from Steady State Voltage Readings
Ensuring that service voltage is within ANSI limits is a basic but important step in delivering power. Sophisticated programs such as Conservation Voltage Reduction (CVR) and volt/VAR optimization require continuous…
UPS Power Quality Case Study
In this white paper, power quality issues that can result from an Uninterruptible Power Supply (UPS) are discussed. Covered are the basic operational concepts of the more popular types of…
Quickly Creating PQ Reports
The ProVision Publication Wizard is a quick way to create finished documents from individual graphs and reports. Use the wizard to create publication templates for different PQ applications, and then…
Measuring Power
The Revolution is a powerful tool for measuring and recording power quality information. With ProVision, there are a wide variety of ways to display and analyze many different types of…
Advanced E-Mail Alerts in Canvass
One of the most popular, and useful, features in Canvass is the Distribution List, which allows any chosen alert or event, from any Canvass-enabled device, to be transmitted by email…
