The Effect of Interference in Location Monitoring of Overhead Power Transmission $ Lines^{1} $
The results are described for experimental studies of interference originating in high-frequency paths of overhead power transmission lines of voltage of 35 kV and above, with location monitoring of the OHLs for the purpose of detecting damage and ice on the wires. The types of interference caused by weather conditions are discussed, and the features of electrical interference and methods of eliminating them are examined. Crosstalk caused to the location sensing by equipment of high-frequency technological communication is analyzed during transmission of signals of relay protection, automated equipment, telemetry, and telephony, and measures for decreasing their effect are discussed. A method is examined for extracting the reflected location pulses against the background of asynchronous fluctuational interference using coherent averaging of reflectograms, and its effectiveness is assessed.
