Abstract

Time-domain electric circuit simulation packages designed for power systems ffiXS r° "*2 ** *"?" ™"*'"y ***<* "^works provided the track and traction line impedance and admittance are known from basic track geometry and material properties. This paper illustrates the use of the EMTP whh^n ^ ?™*"* ™"^ ^ obtain the track impedance and capacitance with special reference to running rail circuits. By comparison with practical measurements it ,s shown that with care, the method is suitable for track impedance, but less precise for running rail circuit capacitance. 1 Introduction Time-domain electrical circuit simulation can be a versatile tool
