Overhead transmission lines are exposed to varying wind loads, which cause different types of vibrations and may gradually affect the mechanical condition of conductors and associated equipment. This master’s thesis examines the physical background of wind-induced vibrations and the possibilities for monitoring them using measurement systems installed directly on the conductor. The aim of the thesis was to identify a correlation between actual vibration and wind measurements based on the relevant theory.
The analysis presents the measurement system and the conductor under consideration, followed by the preparation of vibration and meteorological data and their analysis in the time and frequency domains. The results were evaluated with regard to wind effects, characteristic frequency ranges, and the limitations of the available data. For data with a more suitable temporal resolution, the relationship between wind conditions and measured vibrations is more clearly visible, and the results are consistent with theoretical expectations.
Based on the findings, a concept for a vibration-based conductor health index was also presented, linking vibration measurements to an assessment of long-term mechanical wear. Practical implementation would require longer measurement series, additional mechanical data, and model validation. The proposed approach can complement regular inspections and support condition-based maintenance of overhead transmission lines.
