Automatic generation of construction drawings
Mechanical Design
The software generates drawings for all the component's parts. The most important ones are to scale, and the resulting documentation can be used directly on the shop floor. Data can be exported for CAD systems on request.
Total control over margins
Cost Analysis & Quoting
Instant calculation of material costs based on updated market prices. Ability to compare different versions to choose the most cost-effective one.
Optimize stock
Inventory Management
Automatically imports your inventory, making up-to-date pricing data available within Clever.
Total connection
Industry 4.0 & ERP
Connect the software to your ERP for sending BOMs and to winding machines for automatic transmission of production parameters.
How Clever Suite designs a low-voltage transformer
Electrical, thermal and mechanical calculation in one workflow: from customer data to shop-floor documents.
At a glance

From customer spec to design, no pre-sizing
Enter the data from your customer's specification: the engine calculates, optimises and offers solutions for you to pick the best one. No pre-sizing by the engineer: optimised construction data is selected automatically.
- Single-phase, three-phase and tri-monophase transformers, from 10 VA to 1 MVA and beyond
- Up to 10 windings and every vector group
- Integrated-inductance transformers, zig-zag connection included
- 12-pulse rectifier transformers
- Fully non-standard units
The upper power limit depends only on whether a rectangular core can be used.
Magnetic circuit and core loss
Clever sizes the magnetic circuit and reads the loss curve of the chosen material. In a real 413 kVA design with NOM270 steel at 50 Hz, the operating point is 1.465 T at 1.74 W/kg. Core loss is calculated with proven building factors.
Electrical design and short-circuit voltage
Enter the rating plate data and get the full sizing back: losses, efficiency and short-circuit voltage, with no formulas to double-check by hand.
Short-circuit voltage is calculated from the actual flux. For integrated-inductance transformers the calculation is fully automatic from the target short-circuit voltage.
Temperature rise, layer by layer
Clever calculates the ΔT of every winding layer: it splits the unit into small sections and accounts for heat conduction between sections and between winding and core. Temperature rise is computed for natural and forced convection, with thermal class handling — so you know if it runs too hot before you cut the first lamination.
Cost and materials
Conductor prices change every week. Clever compares the variants automatically and shows you the one that costs less at the same ECO Design efficiency. Its optimisation opportunities cut material consumption by up to 15%.
Enter your material prices and Clever calculates project cost and margin, on every plan. Standard cores and conductors are ready to use; the Pro plan adds your own custom materials and design rules.
From calculation to the shop floor
Scale drawings and the bill of materials are generated from the calculation, not redrawn by hand, and the documents can be used directly on the shop floor. PDF datasheets are ready to attach to a quote.
With ERP integration, bills of materials go to your ERP and production parameters to the winding machines. A complete design takes about 2 minutes on average: engineering teams using Clever are 65% faster.
Transformer design questions
Which transformers can I design with Clever Suite?
Single-phase, three-phase and tri-monophase transformers, integrated-inductance transformers and 12-pulse rectifier transformers, from 10 VA to 1 MVA and beyond. The upper limit depends only on whether a rectangular core can be used.
Does it calculate losses, efficiency and short-circuit voltage?
Yes. From the rating plate data you get losses, efficiency and short-circuit voltage. Core loss is calculated with proven building factors and short-circuit voltage from the actual flux.
How is temperature rise checked?
Clever calculates the ΔT of every winding layer, accounting for heat conduction between sections and between winding and core, for natural and forced convection and with thermal class handling.
Can I use my own materials and prices?
Material prices can be entered on every plan, and Clever calculates project cost and margin. The Pro plan lets you add your own custom materials and define your design rules.
What does the software output?
Scale drawings, bill of materials, PDF datasheets and the technical and production documents. With ERP integration the bill of materials goes straight to your ERP.
How long does a transformer design take?
A complete design takes about 2 minutes on average. Engineering teams using Clever are 65% faster.
Is there free transformer calculation software?
You can send us the parameters: we calculate your transformer for free with Clever Suite and reply within 48 hours.
What is the difference between an online calculator and transformer design software?
A calculator applies a few formulas to values you pick. Clever Suite chooses optimised construction data automatically, calculates losses, short-circuit voltage and layer-by-layer temperature rise, compares the cost of variants and produces scale drawings, bill of materials and datasheets.
