Determination of electromagnetic field in a three-phase system with three single-core power electric cables 110 KV

Abstract

Knowing electromagnetic field inside and in the neighborhood of any power electric cable is very important because of the cable influence on its vicinity. This paper shows the determination of a 3-phase cable system electromagnetic field, applying the COMSOL Multiphysics computer program. Two components of electric field strength vector, potential electric field and induced electric field, are calculated separately, as well as the magnetic field vectors. Induced currents are studied in all constructive elements of cable system. The calculation results are done for the concrete 3-phase system, as a combination of 3 single-core cables XHE-49-A, 64/110kV, with the cross-section 1×1000/95mm2, graphically, together with comments.
