- Abstract:
- In the paper modern CAD (computer aided design) techniques will be used for the analysis and design of a 20 kV combined current-voltage instrument transformer (CCVIT). The magnetic phe-nomena in the complex non-linear electromagnetic CCVIT system will be studied by using the finite element method in the three-dimensional domain and the original program package FEM-3D. The magnetic field analysis will derive the exact CCVIT metrological characteristics. The FEM-3D results are basis for further optimal CCVIT design from metrological aspect by using the stochastic method-genetic algorithm introduced in the original program as an instrument transformer design tool. The objective function during the optimization process is a combination of the CCVIT metrological parameters. Higher accuracy class will be achieved with the CCVIT optimal solution. The CAD results of the finite element method magnetic field analysis and the genetic algorithm optimal design will be experimentally verified through testing of the realized CCVIT prototype in a laboratory.
