Measurement and modelling of radio noise from electric power lines in the rural region surrounding the city of Winnipeg

Abstract

The noise characteristics of transmission lines in the high frequency bands extending to 32 MHz are experimentally investigated. The noise emitted from transmission lines affecting radio reception is analysed with the use of a linear regression technique to model the various classses of power lines classified according to line voltage. These models provide a tool to predict the performance of radio reception in the presence of power line interference. It was observed tha tnoise levels were affected by the line voltage and the load conditions on the line.
