The paper presents the results of field analysis of the shunt reactor 3D structure based on a field method. The magnetic field computations have been carried out for the shell-type and two-limb structure of a one-phase shunt reactor, then to be assembled as a 3-phase unit. The field calculations are performed for 3-D model reactor structures with different number of core slices (different number of air gaps, but with constant intermediate - slice air gap length). The 3D structure of the model reactor is built up, then the mesh is generated for a number of elements exceeding 200 000. The optimal value of the ratio d/g (height of the intermediate-slice air gap/height of the limb slice) and the ratio d/g (height of the intermediate-slice air gap/diameter of the limb) are evaluated leading to minimum values of the weight and capitalized cost of the device.
