The Location of Power Line TYI: Some Reduction Considerations

An oscilloscope method for locating power line television interference is described. The method has several advantages over the use of meter readings, including that of discrimination between noise sources when several are present. Practical information is given regarding equipment requirements and use. Observed noise-pulse patterns are illustrated by photographs. TVI reduction by means of correction and prevention is discussed. TVI can result from corona-precipitation impingement on EHV lines and is an important consideration.
