Advancements in Industry: Demagnetization of Power Transformer Cores
After a power or distribution transformer is disconnected from the power grid or when DC current is applied, such as when a routine winding resistance measurement test is performed, the transformer core is likely to have some remnant magnetism. This remnant magnetism will increase the magnitude of the already high inrush over current levels seen when a transformer is energized. …
Neutral and Ground Harmonic-Induced Power Losses and Correction
In commercial and industrial power systems, harmonic currents can create a variety of issues, including increased power losses and potential damage to equipment. This article describes the various types of power losses associated with neutral and ground harmonic currents with a focus on resistive losses, transformer losses, and dielectric losses in distribution and power factor correction capacitors, and how these …
Unlocking Reliability: A Guide to Low-Voltage Circuit Breaker Maintenance Testing
Circuit breakers in electrical systems play a critical role in ensuring personnel safety, equipment, and systems reliability. These protective devices are designed to interrupt the flow of electrical current in the event of a fault, preventing potential hazards such as electrical fires and equipment damage. Low-voltage circuit breakers encompass a range of types, including insulated case circuit breakers (ICCBs)/molded case …
Advances in Ground Testing
The fundamental principles of electrical ground testing were laid down in the early 20th century, with much of the pioneering work done by Frank Wenner of the U.S. Geological Survey. The most basic and widely used method for measuring soil resistivity bears his name. These principles still underlie ground testing into the present century, but many improvements have been made …
Utilize a Great Resource: NFPA 70E Handbook for Electrical Safety in the Workplace
You may have seen my LinkedIn post about this, but we’ll expand further with some examples to highlight this resource for a better understanding of NFPA 70E. There were two points to the message: Edited by Dean Austin, Chris Coache, and Corey Hannahs, the authors do a great job of providing usable information to us, the electrical workers. It was …
Milestone | Mile·Stone / ˈmī(-e)l-,stōn: A Significant Point in Development
As milestones go, January 16, 2023, might well be considered a significant point in development within our industry. That is when NFPA 70B became effective as a standard recognized by the American National Standards Institute (ANSI). While long accepted as an industry-leading recommended practice, ANSI certification brings changes to NFPA 70B. In this edition of NETA World, our contributors …
