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…
Even vs. Odd Harmonics
Engineered Asymmetry Audiophiles routinely spend thousands of dollars on vintage vacuum tube amplifiers to deliberately inject their music with what power engineers spend millions trying to eliminate: harmonic distortion. Vacuum…
Datacenter Power Consumption II
The explosive growth of datacenter infrastructure in the United States continues to reshape electricity consumption patterns, now constituting a substantial and rapidly growing share of both total load and peak…
Distributed Generation Power Quality Standards
The dramatic proliferation of Distributed Generation (DG) deployments began before power quality (PQ) standards were in place to ensure compatibility in the grid. IEEE 519-2014, a recommended practice for limiting…
Riding Through Voltage Sags with the IEEE 1668 Standard
Voltage sags are the most common power quality issue, and also the most costly for industrial power users. It's not practical for a utility to eliminate all sags, so industrial…
Introduction to Voltage Sags
Voltage sags are short-duration power quality nuisances that can wreak havoc on sensitive electrical equipment. Identifying and classifying sags (as well as identifying their sources) can be a tedious and…
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…
IEEE 1250 Overview: An Introduction to Power Quality
Whether you are new to the study of power quality, or an experienced PQ pro looking for a quick reference, IEEE Standard 1250 is the place to start. IEEE 1250…
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,…
Introduction to Voltage Transients
Transients due to nearby lightning or switching events can cause degradation or failure of almost any electrical equipment. Impulsive transients can pass through transformer interwinding capacitance to appear on the…
