Two service tracks

Routed by what your equipment actually needs

Major repair runs through emergency dispatch and engineering oversight. Diagnostics and quick-turn work runs on a faster, lighter cadence.

Track 01 • Major repair

Equipment failure & emergency response

When transformers fail, won't energize, arrive damaged from shipping, or need structural repair. One engineering-led dispatch.

Bushing failure & replacement

Cracked, leaking, flashed-over, or otherwise damaged bushings.

Tap-changer & voltage-control repair

Tap changers, regulators, controls, motor drives, troubleshooting.

Emergency leak repair

Active leaks - gaskets, bushings, gauges, valves, welds, radiators, oil containment.

Commissioning failure / energization issues

Inspection and testing when a unit won't energize.

Emergency oil processing

Vacuum fill, dehydration, moisture problems, low dielectric strength, oil contamination.

Post-shipment damage repair

Inspection and repair if a transformer arrives damaged, dented, leaking, or with broken accessories.

Flanged-throat / bus-duct modification

Welding and steel fabrication when flanges don't match up.

Transformer fault event / failure

Inspection, electrical & oil testing, damaged-part replacement, repair-vs.-catastrophic recommendation.

Track 02 • Diagnostics & quick-turn

Fast reads on equipment health

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 repair

Small leaks at gaskets, gauges, valves, or accessories.

Accessory troubleshooting

Gauges reading incorrectly, temperature indicators, alarms, monitoring devices.

Oil sampling & basic diagnostics / from $650/test + mobilization

Sampling and lab analysis to flag moisture, contamination, or aging insulation.

Commissioning support

Lower day-rate field assistance during energization of new units.

Emergency oil processing

Single-gasket or small-gasket-set replacements without major teardown.

Pressure & oil-level corrections

Adding nitrogen, topping off oil, restoring proper service condition.

Emergency evaluation visits

Urgent on-site inspection and assessment at a lower rate than full dispatch.

Simple electrical testing

One or two tests to support buying decisions on used equipment or assessing minor damage.

Mobilization quoted per location

In-house welding

One dispatch.
One team.

Most transformer service providers sub out welding work - which means coordinating a separate vendor, splitting accountability, and waiting on schedules you don't control. supertran's lead tech is welding-certified, so tank, radiator, throat, and accessory repairs happen on the same dispatch as the rest of the work.

Welding work is typically expensive and time-critical. Keeping it in-house compresses lead time and gives you a single line of responsibility.

Engineering consulting

Independent oversight - for any transformer, from any factory

Buying from Prolec, Virginia Transformer, a Korean OEM, or anywhere else? supertran's engineers represent your interests at the factory and the site - without selling you the equipment. Especially valuable for hyper-scaler and data-center procurement managing multi-vendor transformer orders.

Where we work

Any factory. Anywhere.

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.

3rd party

Brand-neutral oversight

765 kV

Lead engineer's top experience

19+ yrs

EHV factory & field

Pre-purchase

Vendor Qualification & Evaluation

Independent evaluation of OEMs and their facilities before you commit to a purchase order.

At the factory

Factory Acceptance Test (FAT) Witnessing

Our engineer attends FAT, validates procedure against IEEE standards and your spec, and reports back.

Third-Party FAT Inspection & Oversight

Independent inspection of the unit during the FAT process, with formal written report of findings.

Pre-Shipment Inspection

Final factory walkthrough and condition documentation before the unit leaves the dock.

Test Data Analysis & Reporting

Independent review and analysis of factory test data on your behalf - without setting foot at the OEM, if needed.

At your site

Site Acceptance Testing (SAT) Support

Engineering oversight during on-site acceptance testing after delivery.

Independent Commissioning Support

Third-party commissioning engineer present during energization - your interests, not the OEM's.

Field expertise

Brand-agnostic service, built on 

15+ years of field work

The "any brand" promise has to be backed by people who've actually worked on those brands. Alejandro Gonzalez leads supertran's senior field work - with hands-on experience across the major manufacturers and across multiple national grids, including utility distribution up to 575 MVA.
