This paper deals with construction of device for real-time analysis of traction and recuperative current. The sensing device constructed through utilization of modern microprocessor unit and thus representing full digital system for real time analysis of current spectrum of power semiconductor converter. Content of higher harmonics in these currents must not exceed limits specified in international standard EN 50160, so exact measurement and analysis of this harmonics is necessary. Proposed device uses microprocessor for real time measurement and analysis of traction and recuperative currents. The paper suggests one of the possible modern solutions to the measurement and supervision of traction and recuperative currents in railways electro-traction substations of “Serbian Railways”.
