CETEST is a specialist in EMC testing for the railway industry. We measure and monitor electromagnetic emissions (conducted, inducted or radiated) according to the main international standards, including EN 50121, EN 50238, EN 50500 and EN 50592.
Laboratory tests for verification of standalone components such as traction converters, TCUs, as well as field tests for a full vehicle or infrastructure electromagnetic compatibility verification. Measurements and monitorisation for research and development (R&D), surveillance and homologation purposes. Some examples include:
CETEST performs EMC test campaigns across the entire planet, meeting the expectations of our global clients.
All of our equipment is portable and essentially consists of voltage sensors, Rogowski current coils, different speed and resolution data acquisition systems for harmonic emission testing and magnetic field antennas, electric field antennas, spectrum analysers and electromagnetic interference (EMI) receivers for radiated emission testing.
At CETEST, we help our clients analyse aerodynamic phenomena related to train performance.
CETEST is specialised in several types of aerodynamic tests: slipstream effect, head pressure pulse, maximum pressure variation in tunnels and resistance to motion, amongst others. These tests are performed in accordance with the stipulations of the standards EN14067-4, EN14067-5 and LOC & PAS TSI 2014.
CETEST provides expertise in the field of HVAC and ventilation. We can help during the homologation process as well as to resolve issues related to the HVAC system.
