FIELD: electrical engineering.
SUBSTANCE: inventions group relates to the field of electrical engineering and is intended for monitoring the state of the spark gap installed in the protection circuit of reinforced concrete supports of the contact network of electrified railways. The group of inventions includes a method for controlling the spark gap, which includes gluing an indicator in the form of an RFID tag onto a flat outer surface of the spark gap base in such a way that the RFID tag chips, whose individual codes mark the spark gap, are located above the through holes of the spark gap base, with In this case, in the event of an insulation breakdown, the exhaust of an incandescent highly ionized gas of an electric arc, passing through holes, destroys the RFID tag, which indicates a breakdown of the spark gap and is fixed by a stationary or portable recording device, and a system for its implementation.
EFFECT: increasing the reliability of the power supply system, minimizing the time to eliminate an emergency.
