Abstract
An approach is proposed for determining the current in all elements of a multiwire traction network, which includes a fiber-optic cable with a metal sheath. A method for calculating the current in the shielding conductor is examined as well as a method for determining the traction network resistance of a double-track railway section, taking into account the distributed resistance of the return conductor. The resulting relationships can be used in developing a method for calculating the thermal withstand of optical cables to long-term traction currents, as well as for calculating traction network resistance when designing new and upgrading existing AC railway sections.
