This is the first report to the industry on television interference (TVI) resulting from precipitation on 500 kV transmission lines. The report describes television interference as it relates to corona activity as well as type and intensity of precipitation. Interference evaluation techniques were developed and measurements made on single 2.5" OD, two 1.6" OD and four 0.93" OD conductors.
