ENOTRAC engineers have designed most of the large electrification schemes of the Swiss traction power network, from the Zürich S-Bahn, through the Vereina and NBS Mattstetten-Rothrist lines, to the Lötschberg and Gotthard base tunnel lines. ENOTRAC has also conducted numerous technical studies and investigations for various types of railway systems in Europe, Asia Pacific, Middle East and South America. Our engineers use powerful state-of-the-art simulation and calculation software to design traction power supply systems. These programs simulate the operation of complex DC and AC power supply networks to determine the loads on traction distribution conductors (whether 3^rd rail or overhead), substations, transmission lines, and cables. It is also possible to calculate the thermal behaviour of individual conductors. Such modelling provides the foundation for sound investment decisions, resulting in optimum schemes that meet the technical requirements at minimum cost.

ENOTRAC’s field of expertise includes: electromagnetic field (non-ionising radiation), protection systems, optimised design for earthing and return current circuitry, and protection against stray current and corrosion. We have in-depth experience of demonstration of compliances, as well as design acceptance processes. ENOTRAC equally offers a wide range of services for the planning and implementation of test and measurement campaigns on traction power supply systems. Our data acquisition systems and suite of tools for data analysis have all been extensively verified and validated against measurements.
