Our transport power system design expertise:

Design expertise is provided during the early stages of a project for all electrical and mechanical aspects. Extensive experience has been gained within a wide variety of transit power supplies and on-train interfaces. This allows results from similar in-service equipment to be considered in support of decisions at the early project stages. A design analysis is conducted for all new projects to ensure the power conversion systems comply fully with the functional requirements. In addition, all safety analysis, constructional and material requirements are addressed.

Circuit simulations are conducted with specialist software which support a range of activities as part of the design process.

Electromagnetic Compatibility of equipment features highly in the design process. This includes ‘in-house’ and external testing at accredited test facilities. Equipment compatibility with track signalling circuits and harmonic measurements are also completed ‘in house’. Mechanical integrity is assured with Finite Element Analysis, and further validated at an Accredited Test House.

Fail Mode, Effects, and Criticality Analysis are carried out with a dedicated software suite.

The assembly of the equipment meets the most rigorous requirements and Railway safety standards. All components used in the equipment are service proven in a Rail environment. The PCBs are conformal coated and designed to withstand vibration and contamination. Cable insulation is low or zero halogen in compliance with the appropriate rail approvals. The magnetic components are also specially developed to withstand the traction environment.
