Harmonic magnitude measures the strength of specific higher-frequency components within distorted electrical waveforms, crucial for diagnosing power quality issues caused by non-linear loads like computers and LED drivers.

Smart panels, load management, battery-integrated ranges, and 120V heat pumps could help homes electrify without costly service upgrades, though adoption remains early.

As electricity demand surges due to data centers, electrification, and climate challenges, utilities are investing in infrastructure modernization, addressing supply chain constraints, and adopting new technologies to ensure a resilient, efficient grid for future needs.

In this podcast, Ellen Parson, Head of Content at EC&M, and Kristy Phillips and Adam Akins at Southwire, explore how electrical contractors can improve jobsite productivity, safety, and sustainability through better preplanning, equipment standardization, and collaboration with manufacturers

In the next four years, the number of manufacturers with automated processes such as data capture and analytics, physical production, and after-sales support is forecasted to nearly triple, according to PwC’s February 2026 survey of 443 global manufacturing leaders. According to the research report, the surge in automation will impact everything...

Explore Chapter 7’s organizational changes, including new, deleted, relocated, and renumbered articles, and learn how to navigate its requirements.

Harmonic pollution results from non-linear devices distorting electrical waveforms, causing voltage and current distortions that can damage equipment and reduce power quality. Proper understanding and management are essential for maintaining system reliability.

This article explores the impact of harmonics on industrial electrical systems, highlighting how nonlinear loads create waveform distortions that can lead to equipment overheating, failures, and increased downtime, emphasizing the importance of understanding and managing harmonic pollution.

This article explores the practical aspects of measuring and mitigating harmonics in electrical systems, emphasizing industry standards like IEEE 519 and IEC 61000-4-7, and highlighting methods to restore system balance and compliance.
