As a philosophy and English major who has spent the last 20+ years working in the utility industry,
I often come across topics that challenge me because I don’t have a science or engineering background. This article is an exploration of the basics around online DGA monitors, to better understand the technology and the pros and cons associated with the different options.
Dissolved gas analysis (DGA) is the most widely-used test conducted on transformers while...
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...
Dissolved gas analysis: addressing the challenges of collecting samples BY DONAL SKELLY, GE’s Digital Energy business Dissolved gas analysis (DGA) is a technique for identifying and quantifying the gas formed in oil-filled electrical equipment because of either the natural aging of oil and paper...
The critical importance of power to every aspect of our world cannot be over-exaggerated. It must be generated and distributed effectively to end users, and any disruption in that process means loss of operations, money, and in extreme cases, life. Therefore, the reliability of power creation and...
IntroductionContinuous online monitoring of bushings provides real-time information which can result in the early detection of a possible failure. Challenge: A Major AlarmA prominent U.S. utility was looking for a way to improve system reliability for their 138kV assets. They researched and...
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...
