Abstract :
The paper presents an improved technological solution for the electric drivings of trams KTD, whose aim is to reduce the energetic consumptions and the increase of exploring safeness and travelers comfort. The new solution uses choppers that substitute the accelerator used in the initial technical solution. The analysis of the experimental determinations made over a tram provided with the new equipment (tram no. 106) and respectively over a tram with the old equipment (tram no. 105) from RAT Craiova revealed that the energetic consumptions were reduced to 41.6%. The equipment reliability was also increased, simultaneously with savings in the exploiting costs. The new technological solution includes a monitoring and diagnosis system, that resulted into the diminishing of traffic-faults number, with beneficial effects over the urban traffic fluidity
