Magnetic field of a shielded three-phase busbar system

The paper presents the measurement results of the magnetic field in a shielded three-phase busbar system manufactured by Holduct Mysłowice. The measurements were performed with use of a specific non-directional magnetic field probe. In addition, also theoretical computations were done with use of finite elements. The results roughly agree, but at some probing points the differences are considerable, probably due to inaccurate positioning the probe between the bus bars.
