The most important thing we build is trust


Transformer design in three dimensions. 3D Transformer environment: for transformer and reactor design in three spatial dimensions.

A powerful interface and analysis tool for power systems designers


Cobham offers a number of specialist, high-level design environments that focus the proven computational power of Opera software on to particular application areas.


The environments provide ready-made generic designs, together with application-specific data entry and advanced optimization techniques, all expressed in the language of the application.


The environments provide a strategic framework for the design, analysis and optimization of your electrical products.


The advanced facilities can boost the productivity of your engineers and get your design to market with reduced time and cost.
