Understanding Voltage Stability vs. Voltage Regulation
Voltage stability and voltage regulation are commonly confused concepts, particularly in the context of customer voltage complaints and power quality investigations. These two phenomena differ significantly in both cause and…
Introduction to Ferroresonance
Ferroresonance is a nonlinear electrical phenomenon that can damage transformers, surge arresters, cable insulation, and switchgear — and create dangerous backfeed voltages on conductors that should be de-energized. Although relatively…
Grid Readiness for Data Centers
Global cumulative investment in data centers between 2026 and 2030 is projected to reach $3 trillion. This explosive growth is straining electric grids worldwide. This white paper summarizes the IEEE…
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…
Power Theory in Multiphase Distorted Systems
Introduction “Geometric Foundations of Power Theory for Multiphase AC systems in the Frequency Domain” is a great research article written by Francisco Montoya and others and it clearly explains a…
Best Practices for Photovoltaic Monitoring Setup
The increasing development and use of solar power generation using Photovoltaic (PV) systems introduces new power quality perspectives and challenges. Understanding common analytic avenues with regard to PV systems can…
PQ Canvass — Getting Started
Power Monitors’ PQ Canvass is the premiere way to view and analyze power quality data. Born from Canvass, our first generation cloud-based system, PQ Canvass is a power platform to…
Ferroresonance and Power Quality
Most in the world of power quality are familiar with the concept of resonance in an electrical network as well as the methods for dealing with the issues and byproducts…
Voltage Regulation Analysis With Daily Profiles
If there were no variations in distribution load, system voltage regulation would be a simple task. But Ohm’s law dictates that a change in load produces a change in delivered…
