Telephone-Interference Calculation for Multiconductor Power Lines

Previous work on power-line-produced telephone interference has dealt with the case of a single equivalent power conductor. This paper presents the theory applicable to a multiconductor power line excited by general, linear networks. A self-contained digital-computer program employing these techniques has been written. It rigorously handles the important case of actual communication line-power line crossings. A comparison of the computer results with experimental measurements is provided.
