Electric cooperatives play an essential role in delivering reliable power to the communities they serve. With geographically dispersed systems, aging equipment, limited internal resources, and increasing reliability expectations, co-ops need service partners who understand their operational and budgetary challenges.
MVA provides comprehensive transformer diagnostic testing and field services to help electric cooperatives make informed maintenance decisions, prevent unexpected failures, and extend the life of critical equipment. Whether you need routine transformer oil testing, emergency field support, or help monitoring and maintaining transformers throughout your system, our team can develop a program tailored to your cooperative’s needs.
More Than a Testing Laboratory
Every transformer oil sample provides valuable information about the condition of the equipment. MVA combines advanced laboratory testing with expert analysis to help co-ops understand what their results mean and what steps should be taken next.
Our transformer oil testing capabilities include:
- Dissolved Gas Analysis (DGA)
- Moisture-in-oil testing
- Dielectric strength testing
- Acid number and interfacial tension
- Power factor testing at 25°C and 100°C
- Furan analysis
- Inhibitor content
- Particle count and fault metals
- PCB analysis
- Silicone fluid testing
- Customized testing packages
Our transformer diagnostic experts review test results, identify developing concerns, and provide clear recommendations that can be used to prioritize maintenance. Trending results over time can also help co-ops identify changes in transformer condition before they lead to a more serious problem.
Rush turnaround is available when faster answers are needed.
Convenient Sampling and Reporting
MVA makes the oil sampling process easier through our XQOhm® app and secure online Dashboard.
Using XQOhm®, technicians can identify an asset, scan sample information, add photos, and submit everything electronically from the field. This eliminates handwritten paperwork and helps reduce errors associated with manual data entry.
Through the MVA Dashboard, cooperative teams can:
- Request sample kits
- Manage transformer and equipment information
- Track submitted samples
- Access laboratory reports online
- Review historical testing data
- Share results with authorized team members
For co-ops that need additional support, MVA can also provide professional field sampling.

By providing both laboratory diagnostics and field services, MVA can help co-ops move efficiently from identifying a potential concern to developing and completing the appropriate corrective action.
Support for Systems of Every Size
Every cooperative has different equipment, staffing levels, budgets, and maintenance priorities. MVA can develop a testing and service approach based on asset criticality, transformer design, operating history, and maintenance goals.
We can assist with:
- Establishing a routine oil testing program
- Reviewing and trending historical laboratory results
- Prioritizing transformers for maintenance or further evaluation
- Investigating abnormal DGA results
- Planning repairs around scheduled outages
- Supporting new transformer installations
- Responding to urgent equipment concerns
- Supplementing internal crews with specialized transformer expertise
Our goal is to give cooperative teams the information and support they need to use maintenance resources effectively while protecting the equipment their members depend on.
