This paper describes a new approach for designing with the ANSYS program, including cylindrical, coaxial and alternating current shunts, designed for currents from 10 A to 100 A, which are used as new work standards of the National Research Council (NRC), in the frequency range up to 100 kHz.The heating factor, is one of the more important issues, when determining the dimensions, i.e., the maximum current for which the shunt is intended.Using the ANSYS software package, a model for the current shunt is designed and the distribution of the temperature flux, of the coaxial shunt is analyzed.Further, the main stages of the 3D modeling of the temperature field are considered.The theoretical temperatures of the cylindrical shunt obtained by simulation, are compared with the experimentally determined temperature values, of the resistive shunt, of the same dimensions and characteristics, as carried-out in the laboratory, using the same currents.
