Abstract
The paper considers the problem of calculating short-circuit currents flowing in the metal sheath of the FOCL integrated into the grounding system of the contact network supports. It is used a technique for determining the currents in the metal part of the FOCL for various options for powering the inter substation zone. The conclusions are drawn, criteria are proposed for determining the possibility of using FOCL as an additional conductor from the standpoint of ensuring the estimated service life of a fiber optic cable.
