Brief to Department of Communications regarding effects of proposed broadcast service in the 115-190 KHz band to power line carrier systems / Canadian Electrical Association.: Co23-93/1977E-PDF
"Power line carrier systems are used throughout the world to protect and control large blocks of electric power. Power line carrier is used extensively in Canada; there are more than 2100 radio frequency terminals in operation, representing over 115,000 route miles. The capital invested in power line carrier equipment is enormous. The proposal to be presented by the United States to WARC79 to establish commerical broadcast service on a world-wide basis in the power line carrier frequency spectrum of 115-190 kHz, is viewed with dismay by the Canadian Electric Utilities. The probable interference to power line carrier systems from broadcast transmitters in this band could seriously impair the control and protection of power grids. The Brief describes the characteristics of power line carrier and presents several alternatives to power line carrier. However, owing to technical difficulties, the alternatives cannot be considered as viable solutions and a recommendation is made urging the Department of Communications to vigorously oppose the United States proposal at WARC79."--Abstract.
