HIGH VOLTAGE POWER LINE SITING CRITERIA. VOLUME I. HIGH VOLTAGE POWER LINE TEST RESULTS, ANALYSIS AND APPENDICES
Abstract
The purpose of this contract on High Voltage Power Line Siting Criteria is to determine the various factors involved and their effects on radio noise from power lines so that a communication site can be selected which will not be seriously affected by radio interference from existing lines or from proposed lines in the vicinity of the communication site. Field strength measurements were made from 60 hertz to 1000 MHz on both wood pole and steel tower lines from 2.4 kV to 345 kV inclusive. Some measurements were attempted below 60 hertz without success. Measurements were also made with an artificial gap connected to a phase conductor at the tower. This was done in order to have a controllable and powerful radio noise generator for the measurement of spectra at various distances from the line. These measurements have been applied to estimation or prediction of radio noise with respect to the most important factors of distance from line and the frequency and to other factors such as line height, and antenna height and polarization. The report also includes (1) laboratory measurement of conductor corona type radio noise with conductors of different diameters and different surface conditions (These measurements are applicable in the estimation of the magnitude of radio noise generation by extra high voltage line conductor corona.), (2) laboratory measurements of the frequency spectra of artificial gap-type radio noise generator and corona, (3) a bibliography of American and Foreign literature of importance to the problem of radio noise from power lines, and (4) application of antenna theory to radiation from lines and measurements with different antenna heights.
