The increasing load on the power supply system of electrified railways leads to higher requirements for reliability of power supply. Clarifying the criteria for the operation of the automated system to combat ice formation on the wires of traction power supply to railways in difficult weather conditions is an urgent task aimed at improving the reliability of uninterrupted power supply of rolling stock

Fiber-optic data transmission lines (FOCL) are one of the main parts of automated data transmission control system, which controls technological processes of railway transportation. The lines are subject to powerful electromagnetic effects from traction power supply system. Improving the reliability of the entire system by reducing the electromagnetic influence and the optimal choice of the VOC location is a complex and urgent task, the solution of which will significantly improve the reliability and efficiency of the entire automated complex.
