Progress Report on the HVDC Test Line of the 400 kV-Forschungsgemeinschaft: Corona Losses and Radio Interference

Since spring 1966, statistical investigations of corona losses and radio interference from a dc test line have been performed in the Dossenwald Research Station near Mannheim- Rheinau, Germany. After one year's observation, resulting in 28 000 measurements, the principal influence of weather on these values could be estimated. Additional studies on individual problems by way of short-time tests brought further information. Thus the behavior of this line can be predicted with reasonable accuracy.
