Abstract

EN The magnetic flux densities above the earth surface produced by overhead sagging conductors of complex geometry are estimated. The power line is divided into a series of straight-line segments (spans). The analytical formulas for calculating the 3D magnetic field with respect to a convenient and unique reference system are derived. Moreover the mitigation effects due to the passive loop are also investigated, whereas the mitigation loop can be treated as a two-sagging-conductor closed loop located under the power line.
