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 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 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 monitoring […]

Choosing the Right Transformer Oil Testing Package for Reliable Asset Management

Keeping transformers operating reliably starts with a diagnostic program that matches the needs of each asset. While routine oil testing is an essential part of transformer maintenance, a one-size-fits-all approach often fails to provide the level of insight needed for different transformer types, operating conditions, and reliability goals. At MVA Diagnostics, we offer a comprehensive […]
