Review of Technical Considerations on Limits to Interference From Power Lines and Stations

A summary of all pertinent information necessary in the formulation of a rational technical basis for any consideration of limits to interference from power lines and stations is given in this paper. The paper includes a review of the interference characteristics of power lines and stations, of the characteristics of radio and television signals, quality of reception as influenced by power system interference and finally a summary of various existing interference regulations and transmission line design practices. The technical and economic implications of any regulations are discussed, and finally, an outline is given of the important technical criteria which have to be taken into account in any consideration of interference limits.
