As we step into 2025, I am thrilled to welcome you to the Spring issue of NETA World. I hope you are reading this at PowerTest25, NETA’s premier event bringing together the brightest minds in the electrical power systems industry and offering a platform to learn, share, and grow. The field of electrical power systems continues to evolve, and one …
Storms with lightning are a major cause of electrical system interruption.
Solar energy is a significant factor in today’s electrical energy market. NETA Certified Technicians need to understand how solar panels function and become familiar with best practices for installation, testing, and maintenance. 1. What type of energy do solar panels convert into electricity? a. Chemical b. Nuclear c. Radiant d. Gravitational 2. What type of electricity is generated within solar …

Distance protection measures loop impedances to determine the location of a fault on the protected line. There are six loops: A-B, B-C, C-A, A-G, B-G, and C-G. This article demonstrates how distance protection measures the apparent loop impedance for B-Phase-to-C-Phase and A-Phase-to-Ground faults. The loop impedances for phase-to-phase and phase-to-ground faults are not equivalent due to the presence of neutral …

We’ll get to the punch line first. Your personal safety relies on one person and one person only….and that person is you. Look in the mirror — that’s it. Electricity is a powerful force — one that helps us each and every day in all that we do. With that power comes an element of significant risk: severe injury or …
As we approach the end of another successful year, I want to take a moment to reflect on the achievements and challenges that have defined our industry. This past quarter, we had the privilege of hosting the inaugural Electrical Power Innovations Conference (EPIC), and I’m thrilled to report that it was a tremendous success. EPIC brought together leaders, innovators, and professionals …
In writing my first President’s Desk message I found myself reflecting on those who laid the foundation for the InterNational Electrical Testing Association it is now my privilege to serve as NETA Board President. It is daunting to look back on NETA’s history for insight from the people who built the Association from a concept to a coveted accreditation protecting …
Grounding and bonding are integral parts of an electrical system and must be properly understood, installed, and maintained for maximum safety and performance. Accordingly, the National Electrical Code© (NEC©) focuses on describing, defining, and regulating this element, specifically in Article 250 Grounding and Bonding of Electrical Systems. Grounding electrical systems serve the dual purpose of limiting voltages that might otherwise …
