Sell a 5000 kVA transformer from your Texas site
A 5000 kVA transformer has a 5 MVA rating: kVA means kilovolt-amperes, and MVA means megavolt-amperes. Both describe apparent power capacity, not the equipment’s physical size. Units in this class commonly serve industrial substations, oilfield substations and campuses with substantial electrical loads.
Typical configurations include substation transformers with exposed bushings or connections to adjoining equipment, and three-phase padmount transformers with enclosed cable compartments. Cooling radiators, cable boxes and other accessories can make two units with the same rating look quite different.

Check any rating with the kVA to amps calculator.
Voltage combinations and 5000 kVA transformer specs
Primary voltage is the supply-side voltage; secondary voltage is the output-side voltage. Common combinations can include 12,470 V to 480 V, 13,800 V to 480 V, and 34,500 V to 4,160 V or 13,800 V. Actual suitability depends on the complete nameplate configuration, not just the 5 MVA rating.
For 5000 kVA (5 MVA) transformer specs, include winding connections, frequency, tap settings and impedance. Impedance is the transformer’s opposition to current flow, expressed as a percentage, and matters for fault-current calculations and parallel operation. A matching voltage ratio alone does not establish compatibility.
On liquid-filled equipment, send the cooling designation and every listed capacity rating. ONAN means oil natural, air natural cooling; ONAF means oil natural, air forced cooling using fans. Confirm whether 5000 kVA is the base rating or a fan-assisted rating rather than assuming all listed capacities apply under the same conditions.
Full-load amps at 5 MVA and why buyers check them
For three-phase equipment, full-load current equals kVA multiplied by 1,000, divided by 1.732 times the line-to-line voltage. At 5000 kVA, that is approximately 6,014 A at 480 V, 694 A at 4,160 V, 231 A at 12,470 V and 209 A at 13,800 V.
The corresponding currents are approximately 116 A at 24,940 V and 84 A at 34,500 V. The table below lets you compare these voltage levels. Our transformer kVA-to-amps calculator also helps check current at another nameplate voltage.
Buyers care because current affects the required cable connections, bus, switchgear and protective equipment at a future installation. A 480 V secondary carries much more current than a medium-voltage secondary at the same capacity. These figures describe rated full-load current; available fault current and installation compatibility require separate evaluation.
What affects value and demand for a 5 MVA unit
Demand for this size is tied to projects needing substantial capacity with a usable voltage and connection arrangement. Industrial expansions, campus systems and oilfield power projects can have different requirements. A standard, well-documented configuration is easier to evaluate than a unit with missing ratings or unusual connections.
When you sell a 5000 kVA transformer, value depends on more than its rating. Working condition, voltage combination, cooling stages, accessories, test records and physical damage all affect the evaluation. Location and the work needed to remove and transport it also matter.
A used 5000 kVA (5 MVA) transformer with operating history and recent test results gives a buyer more information than one with an unknown failure. If available, send DGA results—dissolved gas analysis of insulating oil—and oil reports showing PCB status, meaning the presence or absence of polychlorinated biphenyls.
For mixed-capacity lots, identify each unit separately, including any 3750 kVA transformers or 7500 kVA transformers. Similar-looking equipment can have different ratings, so one representative photo is not enough.
Nameplate details and photos to send
Start with a readable, straight-on nameplate photo and overall pictures from several sides. Use our guide to reading a transformer nameplate if the plate contains multiple voltage or cooling ratings. Photograph separate accessory plates when they add information.
Include the following details so we can review the equipment and its pickup requirements together.
- Quantity, manufacturer, serial number, rated kVA or MVA, and whether each unit is new surplus, used, retired or failed.
- Primary and secondary voltage, phase, frequency, winding connections, impedance, taps and cooling ratings.
- Site location, present operating status, known damage, missing parts, and available maintenance or test records.
- Photos of bushings, radiators, controls, cable compartments, connections and the surrounding access area.
Weight, rigging and trailer planning
Use the nameplate for exact listed weights rather than estimating from the 5000 kVA rating. Check whether it distinguishes total weight, oil weight and shipping weight. Drawings can help identify transport dimensions and accessories that affect the shipping arrangement.
Rigging and trailer selection depend on the actual equipment, lifting provisions, site access and load arrangement. Share photos showing overhead obstructions, gates, pavement, the transformer’s position and room for loading equipment. Tell us whether it sits on a pad, inside an enclosure or beside connected switchgear.
The seller or the seller’s qualified electrical contractor must de-energize and disconnect the transformer. We coordinate freight and load-out with the seller. Price, payment terms and pickup details are agreed in writing before anything is loaded.

Frequently asked questions
Is a 5000 kVA transformer the same as a 5 MVA transformer?
Yes. Both ratings describe the same apparent power capacity. Check the cooling stages, though: a nameplate may list different capacities for natural cooling and fan-assisted operation.
Can I sell a failed 5000 kVA transformer?
Yes, we buy failed units as well as working equipment. Describe the failure, known damage and missing components, and include any inspection or test records available.
Does a 480 V secondary change the evaluation?
Yes. At 5 MVA, a 480 V three-phase secondary has approximately 6,014 A of full-load current. Its connection arrangement and suitability differ from those of a medium-voltage secondary.
Should I include radiators, fans and control cabinets?
Photograph and identify all included accessories, whether attached or stored separately. Cooling equipment and controls help establish the complete configuration and what is available for sale.
Can you evaluate a 5 MVA unit still installed at a site?
Yes. Send its nameplate, photos, condition and location, and explain the planned removal. Include access photos so freight and load-out considerations can be reviewed before pickup arrangements are finalized.
