Abstract
Experimental material on detection of breaks and short circuits in electric-power lines (EPLs) obtained by the location method over a number of years is summarized. The features of location diagnostics of overhead EPLs with treelike (6–10 kV) and linear (35 kV or greater) topologies are considered. The methodologies of recognition of location-probing reflectograms with indication of the type and position of an EPL fault are described. The techniques of extraction of reflected location signals against a background of technological interference present in the high-frequency path of a high-voltage EPL are considered.
