In order to improve the efficiency of electrical distribution in commercial buildings, the US Department of Energy (DOE) introduced regulations with more stringent minimums on transformer efficiencies in January 2016. This was covered under the Code of Federal Regulations 10 CFR Part 431.192 and has become more commonly known as DOE 2016. It improved on the previous regulation by requiring 30% lower losses at 35% loading which was determined to be the most common operating...
According to CIGRE A2.34, the dynamic resistance measurement or DRM (OFFLINE) is a test that offers diagnostics for several diverter or selector switch malfunctions such as: contact problems, broken springs, broken transition resistors, poor contact pressure, inadequate transition time, momentary...
Electrically conductive pastes in high-voltage transformers BY LISA RINALDO, Prohm-tect As with other components of North American infrastructure such as wastewater and stormwater systems, much of the continent’s electrical grid faces long-term problems. Aging facilities, rising energy...
For DGA interpretation, faults identified using hydrocarbon gases are considered more serious if they appear to affect paper insulation. That is made explicit in CIGRE technical brochure 771[1]. Production of hydrocarbon gases from the oil by electrical or thermal stress does not significantly...
The Growing Transformer Supply Crisis The global transformer supply chain is facing unprecedented challenges, with utilities worldwide struggling to procure essential equipment due to material shortages, manufacturing delays, and logistical constraints. Transformers are the backbone of electrical...
The Growing Need for Safer and Greener Transformer Oils Transformer oil plays a vital role in the operation and longevity of power transformers, providing insulation, cooling, and arc suppression. Traditionally, mineral oil has been the industry standard due to its effective dielectric properties...
The Growing Concern of Transformer Fire RisksTransformers are critical components of modern substations, playing a vital role in the transmission and distribution of electricity. However, due to the high-voltage operations, flammable insulation materials, and exposure to extreme weather...
The Growing Transformer Supply Crisis The global transformer supply chain is facing unprecedented challenges, with utilities worldwide struggling to procure essential equipment due to material shortages, manufacturing delays, and logistical constraints. Transformers are the backbone of electrical...
Power transformers are critical assets in electrical transmission and distribution networks. Their failure can lead to widespread outages, costly downtime, and potential safety hazards. As transformers age and operate under varying electrical and environmental stresses, degradation becomes...
S.E., Inc. has been providing the very best in Transmission Powerline Construction for over (40) years throughout the Western United States. Brothers Mark, Steve, David, and Craig Sorenson have decided to retire and pursue other interests. Everything in the auction is owned by S.E., Inc. and will...
Monitoring the health of bushings is vital for ensuring the reliability of transformers, especially in high-stakes environments like power grids and industrial facilities. Bushings, critical components of transformers, are prone to various failure modes that can lead to operational inefficiencies...
