We’re excited to share that Scott Reed will be a featured panelist at the 2026 IEEE Power & Energy Society (PES) General Meeting in Montréal, Canada! Scott will join industry experts to present: Understanding What’s Happening to the Transformer as
Effective transformer maintenance starts with the right diagnostic strategy. MVA offers a comprehensive range of transformer fluid testing packages designed to support everything from routine condition monitoring to advanced diagnostics. Our standard testing packages provide a proven foundation, but we
When DGA Tells the Story… Listen. Recent LTC DGA results pointed toward abnormal activity inside this transformer’s OLTC compartment. Elevated gassing patterns, combined with field diagnostics, led us to a planned outage and inspection. What we found confirmed the concern:
The condition of transformer insulating oil is one of the best indicators of overall transformer health. Over time, heat, oxygen, and moisture drive oxidation and chemical changes that degrade both oil and cellulose insulation. Interfacial Tension (IFT) and Acid: IFT
We are proud to announce that Scott Reed, Founder and CEO of MVA, has been honored with the 2026 NETA Alliance Partner Recognition Award for his outstanding contributions to the electrical testing industry. The award recognizes individuals who advance electrical
Furan analysis: a window into transformer insulation health When cellulose insulation in a transformer degrades, it produces furanic compounds that dissolve in the oil. Measuring these compounds gives us a critical insight into the condition of the cellulose insulation without
ASTM D-971 Interfacial Tension of Oil against Water by Ring Method IFT is a fluid test used to determine the presence of oxidation by-products, polar contaminants, and other decomposition products. These can be acids, oxidation intermediate compounds, varnishes, and other
Transformer insulating fluid acts as an insulator for electric and thermal capacities for many electrical equipment. Measurement of dielectric breakdown is a major way to measure the capability of a fluid to withstand electrical stress. In measuring dielectric breakdown, an
