Practical Handbook for the Location, Prevention and Correction of Television Interference from Overhead Power Lines

摘要

This handbook is intended for practical use in the location, prevention and correction of television interferences (TVI) from overhead transmission and distribution lines. The theoretical aspects of interference generation are introduced and practices in design, construction and correction which have proven successful in interference suppression are described in detail. The latest well-proven techniques and equipment for locating fair weather television interference are emphasized. Construction details are provided for recommended test equipment not commercially available. In the case of foul weather TVI, methods are described for improving television reception near transmission facilities. This applies to 60 Hz ac lines where the NTSC (National Television System Committee) method of television transmission is used. Many of the principles discussed apply to other power frequencies and television transmission systems used elsewhere. (ERA citation 12:023715)
