Sounding of Air Power Transmission Lines by the Location Method

摘要

Peculiarities of the location method to sound power transmission lines (PTL) of 6-35 kV in voltage with tree topologies and PTLs with voltages of 110 kV or higher with linear topologies are considered. Methods of recognizing a reflectogram are shown for cases of a short circuit, single-phase-to-ground short circuit, and wire breakage in PTLs. Possibilities of using the location method for PTL sounding are discussed.
