Sell 750 kVA transformer equipment in Texas

Texas Transformer Buyers buys single transformers and whole lots, any brand, whether still in a crate, operating, removed from service or failed. Our yard and office are at 6402 McGrew St, Houston, TX 77087, and we coordinate trucking and pickup with sellers throughout Texas.

At 750 kVA, a transformer commonly serves a distribution center, school or mid-rise building. The rating describes apparent power capacity in kilovolt-amperes, not a fixed amount of usable power for every load. Voltage, configuration and condition determine whether a particular unit fits another installation.

If you are replacing building service equipment, clearing project surplus or retiring a facility, start with photos rather than assumptions about scrap value. A used 750 kVA transformer with readable identification and documented condition gives us more useful information than a capacity rating alone.

Common 750 kVA configurations and applications

A three-phase padmount usually has an enclosed tank with separate high-voltage and low-voltage connection compartments. These units commonly supply buildings from underground distribution circuits. Our padmount transformer buying information covers this equipment category.

Dead-front construction uses insulated, shielded high-voltage connections rather than exposed energized terminals. Loop-feed arrangements provide connections for an incoming and outgoing distribution circuit; they are different from a simple radial-feed arrangement. Clear compartment photos help identify the layout, but have a qualified person obtain them safely.

Unit substation transformers may connect directly to primary switching equipment and secondary switchgear. Tell us whether the sale includes the transformer alone or the connected lineup, since attached equipment changes both the evaluation and the removal plan.

Indoor installations may use cast coil transformers or other medium-voltage dry-type equipment. Cast coil windings are encapsulated in resin rather than immersed in liquid. Include photos of the enclosure, coils, terminals and any visible damage.

750 kVA transformer specs and voltage combinations

Common primary voltages—the incoming supply side—include 12,470, 13,800, 24,940 and 34,500 volts. Secondary voltage is the outgoing load-side voltage, often 208Y/120 or 480Y/277 volts for building service. A 600-volt secondary is another configuration worth identifying accurately.

Examples include 12,470 volts to 480Y/277 volts and 13,800 volts to 208Y/120 volts. These are possible combinations, not specifications shared by every 750 kVA unit. The Y designation means a wye connection, with the second number indicating voltage from a phase to neutral.

Send the actual winding connections, tap positions and impedance from the nameplate. Impedance is the transformer’s electrical opposition to current, expressed as a percentage, and matters when evaluating fault current and compatibility. Also include frequency and any cooling ratings; ONAN means oil natural, air natural, while ONAF adds forced-air cooling.

Full-load amps and why the voltage matters

For a three-phase transformer, full-load current equals kVA multiplied by 1,000, divided by 1.732 times the line-to-line voltage. At the same 750 kVA rating, a lower voltage means a higher current. Use the table below or the kVA-to-amps calculator and chart to compare voltages.

Rounded full-load values are 2,082 amps at 208 volts, 902 amps at 480 volts and 722 amps at 600 volts. On the primary side, the corresponding values are about 35 amps at 12,470 volts, 31 amps at 13,800 volts, 17 amps at 24,940 volts and 13 amps at 34,500 volts.

Buyers care because the secondary current affects compatibility with buswork, cables and switchgear. These calculated values are not breaker settings or permission to energize equipment. They help describe the unit; the complete nameplate and installation design still govern its application.

What affects value and demand at 750 kVA

A 750 kVA transformer buyer needs more than the size to evaluate a unit. Voltage combination, winding material, configuration, age, condition and completeness all affect the offer. Missing doors, damaged bushings, cut terminals or an unreadable nameplate can complicate evaluation.

This capacity can fit building distribution needs between smaller commercial services and larger facility loads. Demand depends on matching the available transformer to a project’s voltage and connection requirements, not just finding a unit labeled 750 kVA. A serviceable unit and a failed unit may be evaluated for different uses.

Maintenance records and test reports help explain condition. For liquid-filled units, include available dissolved gas analysis, or DGA, which examines gases in insulating liquid for signs of internal problems. Send any existing PCB documentation as well; PCB refers to polychlorinated biphenyls, substances relevant to handling certain older insulating fluids.

If the project has mixed sizes, list every unit separately. We also buy 500 kVA transformers and 1,000 kVA transformers, so there is no need to split a whole lot into separate inquiries.

Nameplate photos, weight and pickup planning

For a 750 kVA transformer in Texas, send your nameplate photo, overall photos, quantity, location and condition. Our guide to reading a transformer nameplate can help you identify the details. Include manufacturer, serial number, voltage ratings, phase, frequency, impedance and winding information where shown.

The nameplate lists exact weights; photograph those entries rather than estimating from capacity. Rigging and trailer selection depend on the actual unit, its shipping configuration and site access. Note attached cabinets, radiators, protruding terminals and whether lifting points are accessible.

Tell us about gates, overhead obstructions, pavement conditions and available loading equipment. The seller or the seller’s qualified electrical contractor must de-energize and disconnect the transformer. Trucking and load-out are arranged with you in advance.

Get an offer for your 750 kVA transformer

Call or text (951) 403-5738, email Industrial832@gmail.com, or submit your transformer details for an offer. State whether the unit is operating, disconnected, stored or failed, and describe any known problem.

We evaluate the information and respond with an offer. You get the price, payment terms and pickup details in writing before a truck is loaded.

Frequently asked questions

Will you buy a failed 750 kVA padmount?

Yes. We buy failed units as well as working equipment. Describe the failure, visible damage and any available test findings so we can evaluate the transformer’s condition.

Is a 750 kVA transformer rated at 902 amps?

At 480 volts, its calculated three-phase full-load current is approximately 902 amps. At other voltages, current changes. Confirm the actual primary and secondary ratings on the nameplate.

Can I sell a 750 kVA dry-type unit without its enclosure?

We evaluate incomplete equipment too. Send photos showing the coils, terminals and remaining components, and identify what is missing. Completeness affects the evaluation and loading plan.

Should I separate a 750 kVA unit from its substation lineup?

Send photos of the complete assembly first and identify what you own and intend to sell. We can evaluate the transformer and associated equipment before you arrange removal.

Can you coordinate pickup outside Houston?

Yes. We buy statewide and coordinate trucking and pickup. Provide the Texas location, access details and nameplate weight so freight and load-out can be planned.

Have a transformer to sell?

Send the nameplate photo, a few overall shots and the location. We buy single units and whole lots anywhere in Texas.
