Conductor galloping seriously threatens the safety operation of power transmission lines, especially for the compact transmission lines with small distance between phase conductors. The conductor galloping maximum amplitude is an important parameter for transmission line inter-phase short circuit failure analysis. In this paper, a single degree freedom model is employed to analyze the relationship...
This paper reports on experimental and numerical evaluation of the impedance of busbar systems with ferromagnetic enclosures (trunking). A linear model is developed in which the ferromagnetic material is approximated by a 'linear' material with an 'equivalent' relative permeability. The validation of this linear model is carried out through laboratory measurements on a sample system, and a reasonable...
