Sell a 1500 kVA transformer in Texas
We buy single transformers and whole lots, any brand, including units still in crates and equipment removed from service. If you need a 1500 kVA transformer buyer for a plant shutdown, capacity upgrade or canceled project, start with photos of what you have.
At this rating, equipment commonly serves data halls, manufacturing plants, high-rises and large distribution centers. Across Texas, a unit may become available after a building changes use, a service is expanded or a project leaves surplus equipment behind.
A 1500 kVA rating equals 1.5 MVA. Both describe apparent power capacity, not the transformer's voltage, physical size or remaining service life. Those differences matter when identifying the equipment and evaluating it for an offer.

| 13,800 V | 63 A | Distribution primary / secondary |

Check any rating with the kVA to amps calculator.
Common configurations and voltage combinations
Three-phase padmount transformers generally have a tank and enclosed cable compartments designed for outdoor installation. Dead-front construction uses insulated cable connections rather than exposed energized terminals; loop-feed arrangements provide connections that can support a distribution loop.
Other units form part of unit substations, with a transformer connected to primary switching equipment and secondary distribution gear. Include photos of adjoining sections so we can see whether you are selling the transformer alone or an assembly.
Cast coil transformers and other medium-voltage dry-type units use solid insulation rather than an oil-filled tank. These can serve indoor electrical rooms where ventilation, enclosure design and available space shape the installation.
Common primary voltages, meaning the incoming supply, include 12,470 V and 13,800 V; some systems use 24,940 V or 34,500 V. Secondary voltage is the outgoing supply, often 480Y/277 V or 208Y/120 V, with 600 V used in some industrial systems. Report the actual combination rather than assuming it from the application.
Full-load amps at 1500 kVA
For three-phase equipment, full-load current equals kVA × 1,000 divided by 1.732 × line-to-line voltage. The table below shows approximately 4,164 A at 208 V, 1,804 A at 480 V and 1,443 A at 600 V for a 1500 kVA rating.
On the medium-voltage side, the corresponding values are about 69 A at 12,470 V, 63 A at 13,800 V, 35 A at 24,940 V and 25 A at 34,500 V. These are calculated full-load values, not measurements of what your facility actually draws.
Buyers care because current affects the suitability of terminals, bus connections and related distribution equipment. A 208 V unit and a 480 V unit have the same apparent power rating but substantially different secondary currents. Use the transformer kVA-to-amps calculator to check another listed voltage.
The calculations do not establish breaker settings, available fault current or whether a transformer fits a particular installation. Those decisions require the equipment data and an electrical design assessment.
What affects value and demand at this size
Demand for this size depends on matching an available unit to a project that needs its capacity and configuration. A 1500 kVA transformer can suit a substantial building or plant load, but voltage, winding connection and installation requirements determine whether it is a practical match.
Condition also matters. A used 1500 kVA transformer with readable identification, service records and intact components presents a different evaluation from a failed unit with missing parts or an unknown history. We assess both; describe known problems directly.
Other factors include age, brand, conductor material, enclosure condition, accessories and whether the unit is complete. Impedance, the transformer's opposition to current expressed as a percentage, affects fault-current calculations and compatibility with equipment intended to operate in parallel.
For liquid-filled units, available oil test reports can help explain condition. DGA, or dissolved gas analysis, looks at gases in insulating oil for indications of internal problems. If available, include PCB records identifying polychlorinated biphenyl content; do not guess from age alone.
Nameplate details and photos to send
Clear 1500 kVA transformer specs let us identify what you are offering without relying on cabinet appearance. Take the nameplate photo straight on, close enough to read every line, and add another image if glare hides part of it.
Use our transformer nameplate guide if you need help locating ratings. Along with the nameplate, send these details and views:
- Manufacturer, serial number, manufacture date if listed, kVA rating, phase, frequency and primary and secondary voltages.
- Winding connection, tap range, impedance and cooling designation. ONAN means oil natural, air natural cooling; ONAF means oil natural cooling with forced air.
- Overall photos from several sides, plus accessible views of terminals, bushings, cable compartments, fans, gauges and visible damage.
- Quantity, Texas location, current condition and whether the unit is installed, disconnected, stored outdoors or still in its crate.
- Available test reports, maintenance history and a description of any failure, leaks, missing components or repairs.
Weight, rigging and trailer planning
Do not estimate shipping weight from the 1500 kVA rating alone. Liquid-filled padmounts, substation assemblies and dry-type units differ in construction; the nameplate lists exact weights. Photograph the weight information and identify separate cabinets or accessories included in the sale.
Rigging and trailer selection depend on weight, dimensions, lifting provisions and site access. Share measurements, loading-area photos and details about gates, overhead obstructions, pavement and available lifting equipment. Identify whether adjoining gear must travel separately.
The seller or the seller's qualified electrical contractor must de-energize and disconnect the equipment. We coordinate freight and load-out with the seller, with price, payment terms and pickup details agreed in writing before anything is loaded.

Frequently asked questions
Can you buy a failed 1500 kVA transformer?
Yes. We buy failed units as well as working equipment. Describe the failure and send photos of damaged areas, the nameplate and remaining components so we can assess the actual condition.
Is 1500 kVA the same as 1500 kW?
No. kVA measures apparent power; kW measures real power. The relationship depends on load power factor, so a 1500 kVA nameplate does not by itself establish a 1500 kW operating load.
Will a 480 V unit have the same amps as a 208 V unit?
No. At three-phase full load, 1500 kVA corresponds to approximately 1,804 A at 480 V versus 4,164 A at 208 V. Confirm the nameplate voltage before comparing equipment.
Can I sell a 1500 kVA transformer still installed?
Yes, you can send installed-equipment photos for evaluation. Include access details and your removal plan; the seller or qualified electrical contractor handles de-energizing and disconnection before load-out.
Should I include substation switchgear in the photos?
Yes. Show the entire assembly and identify which sections are included. Photograph each section's nameplate separately so the transformer rating is not confused with ratings on switches or secondary gear.
