FIELD: transport.
SUBSTANCE: invention relates to protection of railway communication cable lines. Proposed device comprises protection units including protection first-stage module connected to communication cable and protection second-stage module connected to communication hardware. Besides, it comprises monitoring unit including comparator, microcontroller and current transducers connected to said comparator. Microcontroller is connected via Ethernet interface to weighman software-hardware device and portable monitoring device. Microcontroller software analyses the results of current comparison in measured circuits with threshold magnitudes in real time mode.
EFFECT: higher safety of communication system.
