Its physical model consist of two hollow cylinders and a solid cylinder with different material properties. In turn, the mathematical model is a system of heat conduction equations with the appropriate set of the boundary, initial and continuity conditions. The problem was solved using the modified Green’s method. As a result, the following characteristics and parameters of the busbar were determined as a functions of frequency: heating curves, local time constants, steady-state current ratings, and stationary temperature profiles. The results were positively verified by finite element method.}, type={Artykuły / Articles}, title={Analysis of the influence of current frequency on the thermal field of the insulated busbar}, URL={http://www.journals.pan.pl/Content/114321/PDF/08_89-97_01219_Bpast.No.67-6_28.02.20_K1_OK_TeX.pdf}, doi={10.24425/bpasts.2019.130896}, keywords={frequency analysis, analytical methods, temperature field, insulated busbar}, }
