Abstract

Aeolian vibration of power line conductors is a known phenomenon but damping it properly can still present a challenge in some cases. What sets Norway apart from most other countries is a large number of long spans, some of them having very high every day tension. Eight out of the ten longest spans in the world are in Norway and the everyday stress goes to 40% of the breaking load. Due to the limitation of existing measurement methods the project of evaluating possibilities of using video recordings to determine the amplitude and frequencies of overhead line vibrations and so far, the results are promising
