Badania homologacyjne nowych i modernizowanych pojazdów trakcyjnych wymagają m.in. pomiaru prądu psofometrycznego według PN-EN 50121-3-1. W artykule przedstawiono układ do wyznaczania tej wielkości, zbudowany w oparciu o mikrokontroler. System charakteryzuje się szybkim uzyskaniem wyniku podawanego w sposób ciągły, np. podczas całego przejazdu badanego pojazdu trakcyjnego oraz dodatkowo łatwością obsługi i małymi gabarytami.

Many high power electronic devices working as main drive and auxiliary inverters are being installed in traction vehicles. It requires to pay particular attention to electromagnetic compatibility (EMC) of traction systems. Certification tests for new and modernized traction vehicles require among others the measurement of psophometric current according to PN-EN 50121-3-1. A system used for determination of this value, built on the basis of microcontroller is shown in the article. The task of this device is to measure (record) vehicle’s supply current, its FFT analysis and calculation of psophometric current in frequency range from 50Hz to 5kHz. Determined parameter has been defined and details related to normative measurement conditions have been specified. Individual blocks of presented system have been discussed, including with current measurement converter (Rogowski coil). Description and remarks related to configuration of used microcontroller were presented as well. Possibilities of using program libraries for FFT scope have been provided and results of initial test have been shown. Possibilities of system presented in the article facilitate significantly determining of measured value in heavy conditions of test site. System is characterized by fast result acquiring delivered continuously e.g. during the whole ride of tested vehicle and additional by service easiness and small gauge.
