Finite Element Modelling of Aeolian Vibrations on Stranded High-voltage OHL Conductors

The problem of Aeolian vibrations has been studied in indoor test-spans for many years. Its relevant standard experimentations have resulted in introducing the Energy Balance Method (EBM) which is the most commonly implemented method in the industry. Besides conductor properties, aerodynamic forces...
