FIELD: power engineering.
SUBSTANCE: proposed device comprises power electronic switch (1), integral local circuit reflectometer (2), current HF pulse generator (3), identical galvanically-isolated generators of high-power currents pulses (4.1-4.n), quantity n of the latter corresponding to the quantity of controlled overhead lines connected with power electronic switch. Besides, integral local circuit comprises controller (5) connected with reflectometer (2), computer-aided dispatcher workstation with computer (6) and light panel (7).
EFFECT: higher efficiency of protection.
