Abstract

This paper deals with the electromagnetic noise emission at radio frequencies (in the range 9 kHz to 1 GHz) into the neighbourhood from an electrical railway system. The study has been conceived in order to obtain a preliminary modelling of electromagnetic emissions due to dynamic interaction between catenary and pantograph which can be considered the source of the largest values of noise emission. The proposed sub-model of the electrical interaction between pantograph and catenary, implemented by using Matlab-Simulink®, is able to describe the complex phenomenon of pantograph current collection during both sliding and bouncing (in presence of electric arc). The electric arc, which is influenced by numerous and interactive variables, is not the only source of ele
