Municipal electric utilities have a direct responsibility to the people and businesses in their communities. Transformer decisions must balance reliability, public accountability, available funding, staffing capacity, and the long-term needs of the local power system.
MVA helps public power providers make those decisions with greater confidence. By bringing together transformer oil diagnostics, equipment expertise, and hands-on field capabilities, we help municipalities evaluate transformer health, plan necessary work, and respond when equipment requires immediate attention.
Make Better Use of Maintenance Budgets
Not every transformer showing signs of age needs to be replaced, and not every developing problem can wait until the next budget cycle. Reliable condition data helps municipal utility leaders determine where maintenance dollars will have the greatest impact.
MVA can help your team answer important questions such as:
- Which transformers should receive immediate attention?
- Is an abnormal condition stable or getting worse?
- Can repairs extend the useful life of the equipment?
- What work should be included in the next planned outage?
- Which assets should be considered during capital planning?
- Does the transformer require additional testing, maintenance, or replacement?
Our diagnostic professionals evaluate laboratory findings alongside available equipment history and operating information. The goal is to provide useful direction, not simply deliver a report filled with test values.
Build a Clear Picture of Transformer Condition
Transformer oil testing can reveal electrical, thermal, and insulation-related concerns that may not be visible during a routine inspection. MVA offers individual tests, testing bundles, and customized programs based on transformer design, fluid type, age, importance, and maintenance objectives.
Available testing includes dissolved gas analysis, moisture, dielectric strength, acidity, interfacial tension, power factor, furans, inhibitor, particle count, fault metals, specific gravity, and PCB analysis.
Transformer oil testing can be used to:
- Establish baseline information for newly acquired or installed equipment
- Monitor aging transformers
- Investigate alarms or unusual operating conditions
- Compare current findings with previous results
- Evaluate equipment before or after maintenance
- Support repair-versus-replacement decisions
- Confirm transformer condition following field work
Rush turnaround is available when your utility needs answers quickly.
Turn Diagnostic Findings Into Action
When testing uncovers a concern, MVA can help your utility move beyond diagnosis. Our field service team performs transformer maintenance, repairs, electrical testing, assembly, and oil processing throughout the United States.
Depending on the equipment and findings, our team can assist with:
- Electrical diagnostic testing
- Leak investigation and repair
- Regasketing
- Bushing replacement
- Load tap changer service
- Vacuum dehydration and dry-out
- Oil degasification and processing
- Hot oil reclamation
- Transformer retrofilling
- Pump and component replacement
- Transformer assembly and vacuum filling
- Commissioning support
- Breaker assembly and maintenance
Having access to both laboratory and field expertise creates continuity from the initial evaluation through the completion of the work.
Add Specialized Expertise Without Expanding Your Staff
Municipal utility departments often manage a wide range of responsibilities with lean internal teams. Some projects require transformer-specific experience, specialized equipment, or additional personnel that may not be available in-house.
MVA can supplement your utility team for a single project or provide ongoing support. We work with your personnel, engineering partners, and other contractors to keep the project organized and aligned with outage schedules.
This support can be especially valuable during:
- Planned substation outages
- New transformer installations
- Unexpected transformer alarms
- Oil leaks or component failures
- Major maintenance projects
- Staff shortages or scheduling conflicts
- Pre-budget equipment evaluations
- Emergency response situations
Organize Sampling and Equipment Records Digitally
MVA’s patented XQOhm® platform replaces handwritten sample paperwork with a digital process. Field personnel can use the mobile app to identify equipment, scan sample barcodes, document the asset with photographs, and submit information electronically.
The MVA Dashboard provides secure access to reports, sample activity, and equipment information. Keeping these records together makes it easier to review previous findings and follow changes in transformer condition.
Municipalities can collect their own samples using XQOhm®, or MVA can send experienced personnel to perform on-site field sampling.
Support That Fits Your Utility
MVA can assist with a single transformer concern, a scheduled field project, or a broader condition-monitoring initiative. We tailor our involvement to your municipality’s equipment, staffing resources, priorities, and available funding.
Whether your goal is to investigate a current issue, improve maintenance planning, or gain a better understanding of transformer condition across your system, MVA provides the technical knowledge and field support to help you move forward.
