INTRODUCTION
In most large electrical systems, generators and power transformers are the two most expensive pieces of equipment. In addition to the capital cost of purchase, these two key devices are also the most critical to continuous and reliable operation of the system.
Consider, for example, the main incoming power transformer of a large industrial plant. Failure of that transformer can result in production losses reaching millions of dollars. If the transformer requires repair or...
Today’s electrical infrastructure in the United States might have been viewed as a work of science fiction when the first commercial power grid was conceived and built in New York’s lower Manhattan in the 1880s. But it didn’t take long for fiction to become fact. Thomas...
IntroductionThere is more to DGA interpretation than comparing the latest gas concentrations to limits in a table or plotting them in a triangle or pentagon to identify the apparent fault type. We have found that the whole DGA history of a transformer must be considered when interpreting its most...
If you have oil-filled transformers, the law requires you to have a spill prevention plan in place, up to and including a secondary containment system to protect the environment and prevent oil from reaching navigable waters. Albarrie and Voltra Technology have partnered up to provide the power...
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...
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 Risks An Electrical Substation Transformer is a critical component 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...
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...
