Abstract

The corona discharge mechanism and the resulting audible noise of high voltage
overhead transmission lines with a nominal voltage class equal or higher than 220kV is largely
solved and published. In the course of reconstructing a 110kV line the local approving authority
has forced the grid operator to investigate the corona noise before and after the reconstruction,
especially the effect of changing from single to bundle conductor.
Therefore an experimental setup in the high voltage laboratory of the Institute of High Voltage
Engineering and System Management of the University of Technology has been build and acoustic
measurements on single and bundle conductor were performed. To prove the impact of typical,
various weather conditions to the corona discharges field tests are also realized. With this results
general predications of the corona audible noise of 110kV high voltage overhead transmission
lines can be derived.
