ADVANCED FEM-3D METROLOGICAL APPROACH TO THE ANALYSIS OF COMBINED INSTRUMENT TRANSFORMER

Marija Cundeva, Ljupco Arsov

Abstract

An advanced and novel numerical method for analysis of combined instrument transformer will be given in this paper. The three-dimensional magnetic field analysis results by using the finite element method will be used for estimation of the metrological characteristics of the transformer. The analytical and the results derived by the original FEM-3D program package will be compared and discussed. This will enable further optimal design of the instrument transformer prototype by taking into consideration the exact mutual electromagnetic influence of both transformation cores (current and voltage measurement magnetic cores) and by using stochastic optimisation techniques.
