Abstract
The paper considers an approach to determining the possibility of integrating a fiber-optic cable with a conductive sheath into a group grounding system as a means of increasing the reliability and safety of DC railroad operation. The criterion for decision making is the heating temperature of the cable elements, determined depending on the magnitude of the flowing current and the time of relay protection operation. As a tool for calculating the temperature of all cable elements, including the optical module with optical fibers, a program using the finite element method as the main algorithm is proposed. The initial data for performing the modeling are the current in the cable, data on the cable design, as well as the technical characteristics of the cable elements.
