Analysis of magnetic characteristics of three-phase reactor made of grain-oriented silicon steel

Flux and iran loss distributions of three-phase reactor are analyzed using the finite element method considering 2-D B-H curves and iron losses in arb itrary directions which are measured up to high flux density, It is shown t hat the total iron loss of reactor yoke does not change so much 65 the yoke dimension, although the local iron loss is increased when the width of yok e is decreased. The experimental verification of flux and iron loss distrib utions are also carried out.
