On Reduction of Eddy Current Losses in a Double-circuit Junction Tower Through Cable Sequencing and Reconfiguration
Journal of Magnetics, Volume 26, Number 2, 30 Jun 2021, Pages 156-161
Abstract
In modern cities, consideration must be given to both the development of electric energy and the improvement
of landscape. Therefore, power technicians usually substitute underground cables for overhead lines. Moreover,
junction towers are always employed to provide this interface between overhead lines and underground cables.
This study focuses on reducing eddy current losses of a power junction tower. The losses in structural steels of a
tower will be computed, and different cable arrangements are discussed by finite element method. Furthermore,
the results indicate that eddy current losses of steels can be reduced by performing cable sequencing and
reconfiguration without any new facilities. The reduction scheme can be useful for reducing eddy current losses
of junction towers.
