Abstract :
While modelling a power supply system for an electric railway traction, knowing equivalent circuits of locomotives supplied this way is an essential issue. In alternating current traction it is important to diagnose, inter alia, processes taking place in transformers installed on electric vehicles. In the article there were presented specific phenomena occurring during the work of mono-phase, multi-winding, multisystem (systems AC: 50Hz, 16.7Hz) laboratory traction transformer. In the paper there were also presented difficulties encountered during the process of identifying multi-port equivalent scheme´s elements of the described device, in which a construction defect occurs.
