Autotransformer Design Software

• Single-phase two-limb autotransformers, with series or parallel connection between coils
• Three-phase autotransformers, vector groups Yy or Yyn
• Fully non-standard units

For every configuration sizing is calculated automatically and the software selects optimised construction data: no pre-sizing by the engineer.

Short-circuit voltage is calculated from the actual flux and core loss with proven building factors. From the rating plate data you get the full sizing: losses, efficiency and short-circuit voltage.

The temperature-rise calculation splits the unit into small sections and accounts for heat conduction between them, for natural and forced convection and with thermal class handling. You review the thermal results before exporting the construction files.

Material cost is calculated instantly from up-to-date market prices, with margin analysis and automatic generation of commercial offers.

Integration with your material stock suggests using leftover material and optimises lamination cutting to reduce scrap. Its optimisation opportunities cut material consumption by up to 15%.

The software generates autotransformer drawings automatically, including frame, insulators and connections, and exports to your mechanical CAD. PDFs and bills of materials are ready to use.

With ERP integration, bills of materials go to your ERP and production parameters to the winding machines. From specification to production-ready design takes less than 5 minutes.
