What we buy
Ranges we buy on this page
Transformer Buyers NC buys used, surplus, failed and obsolete Hammond transformers anywhere in North Carolina. This page covers identification, condition checks and removal planning for plant engineers, facility directors, contractors and crews handling retired equipment.
Hammond dry-type and industrial control units often require a closer look at terminals, enclosure ventilation and machine wiring before removal. A readable nameplate and photographs of the installation help establish what is actually on site.
| Phase | kVA | Voltage | Fluid |

| 3-phase | 15 kVA - 20 MVA | up to 230 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
The engineering behind Hammond
Hammond is a Canadian manufacturer with a long line of dry-type and industrial control transformers. Its compact enclosures and clear nameplates are useful identifiers during plant walkdowns.
The brand also has a strong record on machine-tool transformers, where control circuits and cabinet space shape the installation.
A compact Hammond enclosure does not establish the electrical configuration by itself. We check whether the unit is single or three phase, then compare voltage connections, temperature rise and enclosure type against the installation.
A cabinet-mounted control transformer needs different handling from an enclosed floor-mounted dry-type unit.
Local reality
Installed base across North Carolina
For a Hammond unit removed from a Piedmont machine shop, the surrounding machine can explain more than the enclosure alone. Record whether it served a lathe, milling machine or separate control cabinet.
In Greensboro or High Point, include the building and machine identification with the removal photographs.
At a Charlotte industrial facility or a Raleigh maintenance shop, an enclosed Hammond dry-type transformer may be documented separately from the equipment it feeds. Identify the disconnect, circuit designation and mounting location.
Those details help prevent a retired unit from being confused with an adjacent transformer still in service.
Around the site
Failure patterns worth knowing
Winding insulation aging in hot shops is a known concern for Hammond equipment. Blocked ventilation, accumulated dust and nearby process heat deserve attention when documenting a failed unit.
Darkened insulation or a persistent burned odor should be recorded, but neither establishes the internal failure mechanism without further examination.
Terminal corrosion is another failure pattern worth documenting on Hammond transformers. Photograph affected lugs, screws and conductor ends before disconnected wiring is discarded. A corroded terminal can conceal heat damage at the connection.
Qualified personnel should assess the circuit before anyone opens an enclosure or disturbs a termination.
Where it sits
Nameplate, serial and test records
Hammond's clear nameplates make identification straightforward when the label remains intact. Capture the manufacturer, model, serial number, kVA rating, primary and secondary voltages, frequency and phase designation. Include temperature rise and enclosure markings where shown.
Photograph the whole plate squarely rather than sending cropped images of individual fields.
For a Hammond control transformer still attached to a machine, keep the machine schematic with the transformer photographs. Terminal designations and connection diagrams can resolve uncertain leads.
Existing insulation-resistance results, maintenance notes and failure reports are useful records, provided their dates and test conditions remain attached to the readings.
On the ground
Site inspection
During a Hammond site inspection, the first distinction is between an accessible standalone enclosure and a transformer buried inside a machine cabinet. Document door clearance, mounting bolts, conduit entries and the path to the loading area.
In a tight shop bay, the cabinet opening may govern removal equipment selection.
Electrical isolation belongs to qualified site personnel, not the pickup crew. Before a Hammond unit is released, confirm the site's lockout procedure, absence-of-voltage verification and disconnection responsibility. Photograph loose covers, damaged terminals and missing mounting hardware after safe access is established.
Record enclosure damage separately from reported winding failure.
Local reality
Rigging a Hammond unit
Do not estimate a Hammond transformer's lifting requirements from its compact enclosure. Obtain documented weight where possible and inspect the base, mounting arrangement and any designated lifting points. Sheet-metal covers and ventilation openings are not lifting attachments.
A cabinet-mounted unit may need supported extraction before it can reach a pallet.
For removal from a North Carolina machine shop, plan the route around door thresholds, floor pits and active production aisles. Secure a disconnected Hammond unit against sliding or tipping, and protect exposed terminals during transport.
Larger enclosed units may require a forklift or engineered lift plan based on verified dimensions.
Around the site
Brand value in the secondary market
Hammond identification helps establish the equipment's technical fit for potential reuse, but the name alone does not establish condition. Legible voltage markings, phase information and intact terminals make evaluation more specific.
A machine-tool transformer with undocumented connections needs closer review than one accompanied by its original schematic and maintenance record.
Transformer Buyers NC evaluates Hammond units in working, surplus, failed and obsolete condition. Keep the nameplate photographs, enclosure views and failure description together for each unit, especially during plant closures or machine-line demolition.
Complete records allow the assessment to distinguish an intact dry-type transformer from a damaged control assembly.

Questions
Straight answers
Equipment types
Do you buy failed Hammond control transformers?
Yes. We buy failed Hammond industrial control transformers as well as working, surplus and obsolete units across North Carolina. Identify the machine or cabinet they came from, photograph the nameplate and terminals, and include any report describing insulation damage or terminal corrosion.
Service area
Which Hammond nameplate details should I photograph?
Photograph the complete Hammond nameplate, including model, serial number, kVA, voltages and phase designation. Capture temperature rise and enclosure type if listed. For machine-tool control units, add the connection diagram and terminal markings so loose leads can be assessed against the documented circuit.
Payment
Can a Hammond unit remain inside its cabinet?
Document it in place before deciding how to remove it. A Hammond transformer inside a machine cabinet needs photographs of its mounting bolts, wiring and access opening.
Logistics
Nameplate, serial and test records: what should a seller know?
Hammond's clear nameplates make identification straightforward when the label remains intact. Capture the manufacturer, model, serial number, kVA rating, primary and secondary voltages, frequency and phase designation. Include temperature rise and enclosure markings where shown.
