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
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
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
At MVA Diagnostics, we’re continuing to grow our transformer oil testing 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
Every transformer oil sample contains valuable information about the condition of your asset. Through comprehensive transformer oil analysis, developing problems can often be identified long before they result in unplanned outages, expensive repairs, or premature transformer failure. By analyzing the
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
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
MVA Services is seeking experienced Senior Transformer Technicians to join our nationwide field service team. If you have hands-on experience with power transformer assembly, vacuum filling, maintenance, repairs, oil processing, or electrical testing, you’ll work on challenging projects that help
