Impact Loading – PQ Canvass
Impact loading occurs from the inrush current of large motors, welding apparatus, electric arc furnaces, or similar loads. The current pulses are less than short circuit values but may be…
Interharmonic Analysis with Python
Traditional harmonic analysis in electrical systems has revolved around looking at the spectral content on, well, the magnitudes of harmonic frequency components. The IEEE 519 specification provides guidelines for measuring…
Automatic IEEE 519 Report Generation
The IEEE 519-2014 standard specifies measurements, analysis methods and limits for harmonic voltage and current. The 2014 version is very rigorous with multiple sets of limits, time intervals, statistical groupings,…

ProVision Recording Templates
This white paper covers the creation and use of predefined recording templates in ProVision. PMI recording devices can be initialized with a number of configurable settings. Configurable settings include recording…
Introduction to Solid State Power Transformers
The Solid State Transformer (SST) may be a groundbreaking innovation in electric distribution, replacing the century-old "pole pig" with a modern, active power supply architecture. Although still in the early…
ProVision Customization
The “out-of-the-box” ProVision layout is designed for general use. Fine tuning and customizing the ProVision environment streamlines PQ analysis and maximizes use of the screen workspace. We will explore the…
TDD and IEEE 519:2014
IEEE standard 519 was first released in 1982 and was then updated in 1992 and 2014. It defines limits on Total Harmonic Distortion (THD) as well as Total Demand Distortion…
Viewing PQCanvass Boomerang Data in ProVision
Boomerangs smart grid sensors transmit RMS voltage, current, and power data to cloud-based Canvass and PQCanvass systems. Canvass/PQCanvass provide web-based data analysis tools, email/SMS notifications, and long term data storage…
Measuring and Analyzing Voltage Regulation
Voltage Regulation Basics Utilities are generally required to ensure the delivered steady-state voltage is within the limits specified in ANSI C84.1. Persistent under- or over-voltage can result in customer complaints…
Transferring ProVision Recordings to PQCanvass
We've added a major enhancement to ProVision - the ability to sync recordings with PQ Canvass, PMI's cloud-based PQ data analysis system. The implications of this are profound because you…
