What we buy
Ranges we buy on this page
Transformer Buyers NC buys used, surplus, failed and obsolete 100 kVA transformers anywhere in North Carolina. This page covers identification, testing and removal for plant engineers, school facilities staff, clinic operators and demolition crews handling this size.
A three-phase padmount serving a school wing or light industrial tenant needs more than a readable nameplate. Voltage, fluid condition, access around the pad and documented ownership determine the next steps.
| Phase | kVA | Voltage | Fluid |
|---|---|---|---|
| 1 or 3-phase | 100 kVA | up to 34.5 kV | Liquid or dry |
| 3-phase | 50 - 20,000 kVA | 46 kV | Liquid or dry |

Fast offers
A written offer the same business day, based on your photographs.
Dedicated logistics
Our own crew, trailer and crane, not a brokered haul.
No broker fees
One buyer from first call to cleared pad, with nothing skimmed.
How it works
Six steps from photograph to payment
- 01
Take pictures
Photograph the nameplate, the inside of the cabinet and the tank from both ends. Four frames on a phone are enough to price most units.
- 02
Send them to us
Email or text the photographs with the site address and whether the unit is still energised. We reply the same business day with questions or a number.
- 03
Review the offer
The offer names the unit, the site, the price and the pickup window. It is written, dated and good for thirty days unless the unit changes hands.
- 04
We schedule freight
A crew, a trailer and a crane if the pad needs one. You get the date and the arrival window, and the site does not have to close for it.
- 05
Testing on arrival
Winding resistance, insulation resistance and a turns ratio check, plus oil analysis where the unit is liquid-filled. Results travel with the unit.
- 06
Get paid
Payment is released against the signed bill of sale and the scale ticket, by check or ACH, with the paperwork copy left on site.
What we handle
The parts sellers dread
Rigging
Crane, skates and a route survey for anything that will not roll onto a trailer.
Oil containment
Pans, absorbent and a spill plan before a drain plug is touched.
Bill of sale
A document that clears a lien, a lease or a bankruptcy file, not a handwritten note.
PCB paperwork
Testing and manifesting for pre-1979 oil, handled before the unit moves.
On the ground
Reading 100 kVA
The 100 kVA marking describes apparent power capacity, not the voltage or the actual load connected to the transformer. On a three-phase unit, record both winding voltages, the connection diagram and frequency.
A photograph of the complete nameplate is more useful than a close-up showing only the capacity number itself.
At 208 volts, a three-phase 100 kVA rating corresponds to approximately 278 amperes; at 480 volts, it corresponds to approximately 120 amperes. Those figures describe rated secondary current, not permission to disconnect cables.
The school or clinic electrician must establish isolation, verify absence of voltage and follow the applicable grounding procedure.
Local reality
Where this size sits in the state's industrial base
A 100 kVA three-phase padmount can serve a school wing, a clinic or a light industrial tenant rather than an entire manufacturing campus.
Around Greensboro and High Point, tenant renovations may leave a dedicated transformer disconnected after lighting, process equipment or HVAC loads move to a different electrical service arrangement.
In Raleigh or Charlotte, a clinic expansion can change the service arrangement even when the original 100 kVA unit still operates. Ownership needs checking before removal: a pad beside a building may hold utility-owned equipment.
Duke Energy service records or the applicable municipal utility documents help establish who controls the transformer.
Around the site
What it weighs
Shipping weight for a 100 kVA transformer is roughly 900 to 1,400 pounds, although the actual design controls the lift. Read the nameplate or manufacturer's drawing before choosing rigging.
A fluid-filled tank, steel compartment and attached radiators contribute weight that cannot be judged reliably from the size of the cabinet.
A listed shipping weight may not describe the exact condition found on a North Carolina demolition site. Missing fluid, removed doors or attached cable can change the lifted load.
Record what remains on the 100 kVA unit, and use documented weight rather than estimating from the concrete pad's footprint alone.
Where it sits
Moving it
A 10-ton crane is comfortable for this roughly 900- to 1,400-pound unit under suitable lift conditions, but the pad is usually the constraint. Radius, boom configuration and ground support still govern capacity.
A school courtyard may leave less usable setup space than the crane operator needs for outriggers and access.
Before lifting a 100 kVA padmount, check designated lifting points, disconnected elbows, grounding conductors and any anchor bolts hidden at the base. Keep rigging clear of bushings and cabinet doors.
At a clinic, coordinate truck placement with ambulance access, then confirm the route from the pad to the loading position.
On the ground
Voltage pairings
A 100 kVA nameplate may show a medium-voltage primary feeding 208Y/120 volts or 480Y/277 volts. Record the exact primary rating rather than describing it as simply distribution voltage.
A 12,470-volt winding and a 13,200-volt winding are not interchangeable descriptions, even when their padmount cabinets look alike from outside the enclosure.
For a school wing using 208Y/120 volts, note the neutral terminal and the winding connection shown on the diagram. A light industrial tenant using 480Y/277 volts requires a different record.
Tap position, primary configuration and bushing arrangement belong with the 100 kVA identification photographs, not in a guessed equipment description.
Local reality
What we test
Evaluation of a disconnected 100 kVA unit starts with its nameplate, service history and visible condition. Look for a leaking drain valve, damaged bushing, displaced gasket or heat discoloration inside the compartment.
Electrical testing may include winding resistance, turns ratio and insulation resistance, with results interpreted against the transformer design.
On a fluid-filled 100 kVA padmount, fluid records and appropriate sampling can help distinguish moisture contamination from other problems. A failed bayonet fuse alone does not establish that the core and windings are damaged.
Test scope depends on safe access, failure history and whether the school or clinic retained maintenance records.

How we value it
Our buying evaluation of a 100 kVA transformer considers verified ownership, exact voltage pairing, construction, condition and removal requirements. An intact three-phase padmount with readable records presents a different case from a fire-damaged tank with missing bushings.
Photographs should include the nameplate, cable compartment, tank seams and all sides of the pad.
For North Carolina removals, access can matter as much as the 100 kVA rating: locked school gates, clinic traffic and a confined pad affect the handling plan. We buy failed and obsolete units as well as operating equipment.
Identify fluid status, known contamination and any restrictions before arranging removal from the site.

Questions
Straight answers
Equipment types
Can you buy a failed 100 kVA padmount?
Yes. Transformer Buyers NC buys failed 100 kVA padmounts in North Carolina. Describe the failure, including a blown bayonet fuse, leaking tank or damaged bushing, and provide available test records. The unit must be safely disconnected, and ownership must be established before removal.
Service area
Is a 10-ton crane enough for this size?
A 10-ton crane is comfortable for the typical 900- to 1,400-pound shipping weight under suitable conditions. The lift plan still depends on radius, boom configuration, rigging and ground support. Restricted access around a school or clinic pad can be the controlling issue.
Payment
What records identify my 100 kVA transformer?
Provide the complete nameplate, serial number, voltage diagram and any maintenance or fluid records. For a three-phase school or clinic padmount, include photographs of the cable compartment and pad access. Utility service documents may be needed to distinguish customer-owned equipment from utility-owned equipment.

Voltage pairings: what should a seller know?
A 100 kVA nameplate may show a medium-voltage primary feeding 208Y/120 volts or 480Y/277 volts. Record the exact primary rating rather than describing it as simply distribution voltage.
