Use of Location Probing to Detect Damage to the Wires of High-Voltage Electric Transmission Lines

Abstract

Experimental data on the detection of short circuits and wire breaks on 35 – 220 kV overhead electric transmission lines acquired over the course of 20 years of research by a location method are summarized. Techniques that may be used to analyze reflectometer patterns in location probing of transmission lines in order to identify the type and location of wire damage are described. Features involved in the detection of short circuits on existing 35, 110, and 220 kV lines are considered separately. Methods for the detection and display of different types of short circuits and line breaks on existing electric transmission lines are discussed.
