FIELD: electricity.
SUBSTANCE: invention is intended to solve a technical problem concerning the method for determining places of damage of branched overhead transmission line (TL) in form of ice deposit on cables with accuracy up to a part of TL. How to determine places of damage multiended overhead transmission line in the form of ice deposit on cables, namely, that at the beginning of TL and at the end of each branch and TL branching nodes devices for the control of current and voltage are installed. Each device registers the arrival time of the leading edge of voltage surge in a single time scale synchronized with the satellite signals of the global positioning system. Then the recorded time values are transmitted to the control center by all devices for the purpose of their processing.
EFFECT: increase speed, convenience and accuracy of determining places of damage.
