Manufacturing · Transformer Manufacturer Management Software

One system for transformer tenders, core and coil build, loss tests and dispatch.

Tenders, design sheets, CRGO silicon steel coils, winding strip, build stages, routine tests, inspection calls and dispatch sit in one record per unit. The kVA rating, the quoted no-load and load loss figures, the coil lot and every ratio and resistance reading stay with the unit from enquiry to nameplate. A warranty query years later gets answered from that record.

  • Rating ranges, material rates and test sheet layouts loaded as you quote
  • Open orders, units in build and stock brought across
  • Loss limits and test rules reviewed with your own design and quality staff

The system prices tenders and stores the loss limits promised to each buyer. It books CRGO steel lots and winding copper to every unit, then follows the unit through routine tests and inspection. Rating plates, test reports and service history stay linked to the serial, so a complaint years later opens the original design sheet.

Where it breaks today

What goes wrong before the software.

Loss commitments sit in the tender folder

The buyer’s loss limits are written in the offer. The test bay sees only the design sheet. A unit can pass ratio, resistance and impedance checks and still miss the promised no-load loss, which triggers a penalty clause months after dispatch.

Steel offcuts hide the real consumption

Slit widths, lamination offcuts and scrap from the cut-to-length line are estimated by eye, so core steel cost per unit is a guess. When a core shows high no-load loss, nobody can name the coil lot behind it.

Winding sections stop for a reel

Copper strip, round enamelled wire, kraft paper and pressboard come off open reels. A reel runs short halfway through a high-voltage coil. The winding section stops and waits for a supplier call that nobody planned.

Drying and tanking are not scheduled

Vacuum drying ovens and oil filling bays are shared. Units queue by whoever shouts loudest, one unit’s drying cycle hides behind another’s, and a finished active part sits on the floor absorbing moisture.

Test values are retyped three times

A reading goes from bench paper to the test report to the rating plate, typed fresh each time. One mistyped impedance value reaches the customer and comes back as a complaint.

Repairs and rewinds have no history

A returned unit is opened and rewound without the original design sheet to hand. Nobody knows the old tap range, the conductor size or the insulation class. The second repair starts from nothing.

How it runs

How the work flows through it, step by step.

  1. 1

    Tender

    A buyer sends rating, ratio, vector group, impedance and loss limits. The unit is priced from steel, winding copper, oil and tank, and the loss commitments are stored with the offer.

  2. 2

    Design release

    The design office issues core dimensions, coil data and the tap range. Buyer comments are logged round by round, and only the approved revision goes to the shop.

  3. 3

    Material booking

    CRGO coils and winding wire are booked to the unit by lot and weight. A shortage shows against the unit before the cut-to-length line starts.

  4. 4

    Core, coil and tanking

    Laminations are cut and stacked with mitred joints. Coils are wound and fitted, then the active part is vacuum dried, tanked and filled with oil. The supervisor marks each stage complete.

  5. 5

    Test and inspection

    Routine tests are entered against the promised values. A buyer’s inspector is booked, and the outcome is saved to the unit.

  6. 6

    Dispatch and service

    Rating plate, test report and packing list go out with the unit. Later repair, rewind or warranty calls are logged against its serial.

Modules

What is inside.

Every module can be switched on, left out or changed to match how your team already works.

Transformer tenders

Cost a unit from core steel, winding copper, insulating oil and tank fabrication, and keep each revision of the offer that went to the buyer.

Loss commitment register

Store the no-load loss, load loss and impedance limits promised to each buyer, beside the tender that made the promise.

Design sheet control

Hold core, coil and tap data per unit, with each buyer comment round and the released revision.

Core steel lots

Receive CRGO coils by lot and weight, and book cut laminations and slitting scrap to each core.

Winding wire and insulation

Track copper strip, round wire, kraft paper and pressboard by reel, with consumption per coil.

Build stage board

Show which units are in cutting, stacking, winding, drying, tanking or oil filling. Late ones stand out.

Drying and oil bay schedule

Plan vacuum oven cycles and oil filling slots across the units that need them.

Routine test entry

Enter ratio, vector group, winding resistance, loss and impedance readings and compare each with its commitment.

Inspector visits

Book buyer and third-party inspectors against finished units and keep their outcome.

Plates and test reports

Print rating plates and test reports from the stored readings. Nothing is retyped.

Repairs and rewinds

Log returned units against the original serial and design sheet.

Solutions inside

The business modules it is built from.

Each one is also available on its own, or inside a system built for you.

  • Estimate/Quotation Management

    Offers are priced from steel, winding copper, oil and tank for each rating, and every revision sent to a buyer is kept beside the loss figures promised.

  • Workflow and Approvals

    Core and coil sheets go through buyer comment rounds, and only the released revision reaches the core shop and the winding section.

  • Batch and Serial Tracking

    CRGO coils are received by lot and weight, and the coil lot used in each core stays visible on the unit’s record for any later loss dispute.

  • Stock Tracking and Alerts

    Copper strip, round wire and kraft paper are held by reel, drawn to coils, and flagged when a reel will not cover the next high-voltage coil.

  • Production Planning

    Vacuum oven cycles and oil filling slots are planned across units, so a finished active part does not sit waiting behind another one.

  • Work Order Management

    Each unit moves through cutting, stacking, winding, drying, tanking and oil filling, with the supervisor marking every stage complete.

  • Quality Control

    Ratio, resistance, loss and impedance readings are entered per unit against the promised values, and a unit above its limit is flagged at once.

  • Service Reports and Proof of Visit

    A returned transformer is logged against its original serial, with the repair findings and the new winding recorded in a service report.

Services

How we would put it in.

Setup, data migration, integrations and anything built on top.

Who uses it

One system, each person sees their part.

For tender engineers

Price units and record the loss figures the plant has promised to each buyer, so the design office and the test bay see the same limits.

For design staff

Release core and coil sheets and handle buyer comments on every revision.

For core and winding supervisors

See which units have steel and wire booked, and mark each stage done as the stack, coil or tank moves on.

For the test bay

Enter readings per unit and know at once whether a loss is above its limit.

For the stores and dispatch team

Receive steel and wire, and match plates, reports and packing lists before a unit leaves the gate.

Reports

The numbers the owner asks for.

  • Units by build stage and rating
  • Promised against measured losses per unit
  • Core steel and wire consumed by order
  • Inspector bookings and results
  • Units waiting on material
  • Repairs open by buyer
Good fit

Who this is built for.

  • Makers of distribution transformers for utilities
  • Plants building power and furnace transformers to order
  • Firms producing dry type and cast resin units
  • Workshops that build and also rewind transformers
  • Manufacturers who bid for tenders with loss penalties
Honest answer

When it is not the right choice.

  • A shop that only repairs and rewinds small units may prefer a lighter job register.
  • Dealers who buy finished transformers and resell them need stock and invoicing, not a build record.

Common questions

Questions owners ask before a demo.

Does it compare measured losses with the tender?

Yes. The tender stores the no-load and load loss promised, and the routine test enters the measured figures beside them. A unit above its limit is flagged before the test report is printed.

How is silicon steel traced to a unit?

Coils come in by lot and weight. Cutting books laminations and scrap to each core, so the unit record names the coil lot that built it. When a finished unit tests hot, the grade and lot of its laminations are already on file.

Can we plan drying ovens and oil filling bays?

Yes. A schedule shows which units wait for a vacuum oven cycle and which for oil filling. The supervisor moves a unit between slots, and the stores, test bay and office all see the change.

Where do copper and paper stocks appear?

Winding strip, round wire, kraft paper and pressboard are held by reel. Coil consumption is booked to the unit, and a short reel warns the winding section before it stops.

How are inspector visits handled?

A finished unit is attached to a visit with a date and an inspector’s name. The result, and any rework required, is saved on the unit.

Can plate details be printed from the test record?

Rating, ratio, vector group, impedance and serial print from the stored unit data. The plate template is yours.

What happens to a unit returned for rewinding?

It is logged against its original serial and design sheet, so the repair team sees what was built. The new winding is recorded as a fresh stage.

Do you keep type test certificates?

Yes. Reports from your chosen testing house can be attached to a design family. Which tests apply, such as lightning impulse or temperature rise, is agreed with your own staff.

Can existing order history be loaded?

Yes. Orders in build, past unit serials and stock can be imported from your sheets. Your accounts staff check the figures before a live order is taken.

What does an evaluation look like?

You bring a recent tender and its test sheet and see them handled on the system. A written proposal follows when users and modules are known.
