TWO SERVICE TRACKS
From a quick diagnosis
to a critical repair.
Major repair runs through emergency dispatch and engineering oversight. Diagnostics and quick-turn work runs on a faster, lighter cadence.
EMERGENCY & MAJOR REPAIR
Get back online.
When transformers fail, won’t energize, arrive damaged from shipping, or need structural repair. One engineering-led dispatch.
- Bushing failure & replacementCracked, leaking, flashed-over, or otherwise damaged bushings
- Tap-changer & voltage-control repairTap changers, regulators, controls, motor drives, troubleshooting
- Emergency leak repairActive leaks at gaskets, bushings, gauges, valves, welds, and radiators; oil containment
- Commissioning failure / energization issuesInspection and testing when a unit won’t energize
- Emergency oil processingVacuum fill, dehydration, moisture problems, low dielectric strength, oil contamination
- Post-shipment damage repairInspection and repair if a unit arrives damaged, dented, leaking, or with broken accessories
- Flanged-throat / bus-duct modificationWelding and steel fabrication when flanges don’t match up
- Transformer fault event / failureInspection, electrical and oil testing, damaged-part replacement, and a repair vs. catastrophic-failure recommendation
DIAGNOSTICS & QUICK-TURN
Know where you stand.
When you need eyes on a unit fast, a single test before a decision, or quick-turn repair work that doesn’t need a full project.
- Minor leak repairSmall leaks at gaskets, gauges, valves, or accessories
- Accessory troubleshootingGauges reading incorrectly, temperature indicators, alarms, monitoring devices
- Oil sampling & basic diagnosticsSampling and lab analysis to flag moisture, contamination, or aging insulation. From $650 per test, plus mobilization.
- Commissioning supportLower day-rate field assistance during energization of new units
- Gasket replacementSingle-gasket or small gasket-set replacements without major teardown
- Pressure & oil-level correctionsAdding nitrogen, topping off oil, restoring proper service condition
- Emergency evaluation visitsUrgent on-site inspection and assessment at a lower rate than full dispatch
- Simple electrical testingOne or two tests to support buying decisions on used equipment or assess minor damage
IN-HOUSE WELDING
One dispatch.
One team.
Most transformer service providers sub out welding, which means coordinating a separate vendor, splitting accountability, and waiting on schedules you don’t control. Our lead tech is welding-certified, so tank, radiator, throat, and accessory repairs happen on the same dispatch as the rest of the work.
Welding is typically expensive and time-critical. Keeping it in-house compresses lead time and gives you a single line of responsibility.
WHAT WE WELD IN THE FIELD
- Leaking tank seams
- Leaking radiators
- Shipping damage
- Damaged brackets or flanges
- Cracked covers
- Cable-box throat repair
- Bus-duct repair
- Forklift / rigging damage
- Accessory damage
- Custom steel fabrication
INDEPENDENT ENGINEERING CONSULTING
Your interests.
Any factory.
Anywhere.
Buying from Prolec, Virginia Transformer, a Korean OEM, or anywhere else? Our engineers represent your interests at the factory and on site, without selling you the equipment. Especially valuable for hyperscaler and data-center procurement managing multi-vendor transformer orders.
Before you buy
- Vendor qualification & evaluationIndependent evaluation of OEMs and their facilities before you commit to a purchase order
At the factory
- Factory acceptance test (FAT) witnessingOur engineer attends FAT, validates the procedure against IEEE standards and your spec, and reports back
- Third-party FAT inspection & oversightIndependent inspection during FAT, with a formal written report of findings
- Pre-shipment inspectionFinal factory walkthrough and condition documentation before the unit leaves the dock
- Test data analysis & reportingIndependent review of factory test data on your behalf, without setting foot at the OEM if needed
At your site
- Site acceptance testing (SAT) supportEngineering oversight during on-site acceptance testing after delivery
- Independent commissioning supportA third-party commissioning engineer present during energization: your interests, not the OEM’s
FAT witnessing, vendor evaluation, and pre-shipment inspection happen at the OEM’s facility: in Texas, Mexico, Korea, China, India, Europe, or wherever your transformer is being built.
