Abstract Results of radio interference (RI) level measurements on the first 735-kV line of Hydro Quebec are presented. The cumulative frequency of RI levels for the period from 1 October 1965 to 17 July 1966, was studied. An approximation of this curve by three uniformly distributed meteorological conditions, and the distribution curve of absolute humidity are presented. An ensuing equation for the evaluation of RI levels in terms of temperature and relative humidity is included. The rate of change of RI levels with the maximum surface gradient on the conductors is reported. Frequency spectra and lateral profile measured at mid span are shown. The evaluation of RI levels using a published method is also illustrated.
