In order to study the effect of pantograph bounce on railway traction chain a global model including the power supply, catenary, transformer and effects of pantograph bounce has to be established. In this paper, pantograph bounce model considering arc model including all significant parameters such as relative airflow, variable disconnection length is presented. Pantograph arc phenomenon is analyzed in the shape of global model of power input of traction. Model is established using bond graph in order to express differential system of equations that can be easily implemented on numerical simulators. Simulation results are compared with experimental results from real train.
