Abstract: In the paper an advanced CAD (computer aided design) methodology for measurement uncertainties estimation of a combined current-voltage instrument transformer (CCVIT) will be presented. The metrological parameters of the CCVIT are influenced by many variables, mostly introduced by the non-linearity of the very complex CCVIT electromagnetic system. The electromagnetic field distribution in the CCVIT 3D domain will be determined by using an original program package FEM-3D (finite element method) developed at the Faculty of Electrical Engineering and Information Technologies (FEIT)-Skopje. The FEM results will be used for further metrological optimal design of the CCVIT by using the genetic algorithm. The FEM-3D estimated CCVIT metrological uncertainties will be experimentally verified through actual test results recorded in a laboratory.
