AERODYNAMICALLY UNSTABLE OSCILLATIONS OF ICE-LADEN OVERHEAD TRANSMISSION LINES

, and . Energetika l Transport, 29 (2): 103-109 (1991)

Abstract

We present a method for investigating the stability oC overhead transm.issiOn llDe ·oscillatio~s using a minimum of simplifying assumptions. We suggest a generally appli"':lble criterion for the existence of unstable line oscillations. We evaluate the stability of a group of three wires at various angles of wind incidence and compare the resülts with field test data.
