Why Trending DGA Results Is More Important Than a Single Test
Dissolved Gas Analysis (DGA) is one of the most valuable diagnostic tools available for assessing the condition of oil-filled power transformers. By measuring gases dissolved in transformer oil, DGA can provide indications of conditions such as overheating, partial discharge, arcing, and insulation degradation. However, while a single DGA test provides valuable information, the real diagnostic […]
Congratulations to Jenaphyr on her new role with MVA!
After being a member of our transformer oil diagnostics laboratory team, Jenaphyr has transitioned into a new position with our Inside Sales team at MVA’s corporate office in Canton, Ohio. Her experience in the laboratory gives her a strong understanding of our transformer oil testing and diagnostic services, as well as the needs of the […]
PCBs in Transformer Bushings: What Happens After a Bushing Leaks or Fails?
When evaluating the PCB status of a transformer, the oil in the main transformer tank is typically the primary fluid tested. However, older oil-filled transformer bushings can contain insulating fluid with PCB concentrations that differ from the oil in the main tank. Under normal operating conditions, routinely sampling the oil inside a sealed bushing is […]
Transformer DGA Testing: 5 Common Mistakes to Avoid
Dissolved Gas Analysis (DGA) is one of the most valuable diagnostic tools available for evaluating the condition of oil-filled transformers. By measuring gases dissolved in the insulating fluid, DGA can help identify developing thermal and electrical conditions before they lead to more serious equipment problems. However, collecting DGA data is only part of the process. […]
How to Determine if Your Transformer Oil Contains PCBs
Determining whether transformer oil contains PCBs (polychlorinated biphenyls) is an important part of managing older transformers and electrical equipment. Although PCBs have been restricted for decades, they may still be present in older insulating fluids or equipment due to historical use, previous servicing, fluid handling, or cross-contamination. The only reliable way to determine whether PCBs […]
Build Your Career in Transformer Oil Diagnostics
At MVA Diagnostics, we’re continuing to grow our laboratory team and are looking for a skilled chemist who is passionate about analytical science and making a real impact on the reliability of the electric power industry. Every transformer oil sample that enters our laboratory provides valuable insight into the health of critical electrical assets, and […]
Every Transformer Oil Sample Tells a Story
Every transformer oil sample contains valuable information about the condition of your asset. Through comprehensive transformer oil diagnostic testing, developing problems can often be identified long before they result in unplanned outages, expensive repairs, or premature transformer failure. By analyzing the condition of the insulating oil, utilities and industrial facilities gain the data needed to […]
Transformer Condition Monitoring: Which Tests Matter Most?
Reliable transformers usually don’t fail overnight. In most cases, they provide warning signs long before a failure occurs, if you know where to look. Transformer condition monitoring is the process of evaluating the health of a transformer using diagnostic testing and trend analysis. Rather than waiting for equipment to fail, asset owners can use condition […]
Scott Reed Presents Transformer Aging Session at the 2026 IEEE Power & Energy Society General Meeting
At the 2026 IEEE Power & Energy Society General Meeting, MVA Diagnostics Founder and CEO Scott Reed had the opportunity to present “Understanding What’s Happening to the Transformer as It Ages,” a technical session focused on the aging process of power transformers, condition assessment, and strategies for improving long-term asset reliability. The session generated valuable […]
