Abstract. The paper proposes the innovative system of connecting digital terminals to a personal computer of a traction substation and a power dispatcher via remote access thus expanding control and observation over the system and facilitating the operation with In-Ter device. The real time work of In-Ter terminals can be performed by a power dispatcher and can be monitored by an engineer of the technical department of the energy service of an enterprise. This option will allow obtaining useful information quickly and changing the protection settings of a terminal if necessary, analyzing the compliance of loadings, emergency currents and settings in the technical department of the energy service of the enterprise to decrease cases of false activation of protection.
