How do you choose the optimal transformer for electric trains?

Selecting the optimal transformer involves assessing voltage requirements, power ratings, physical constraints (size and weight), efficiency, and environmental conditions. Compatibility with the train’s electrical systems and compliance with regulatory standards are crucial. Considerations include thermal performance, cooling methods, insulation materials, and mechanical robustness. Lifecycle costs, including maintenance and energy losses, are evaluated. Collaboration with manufacturers and adherence to industry best practices ensure the chosen transformer meets performance and safety requirements.
