Analisa Efek Sebaran Fluks pada Sambungan Mitred dan Butted Inti Transformator dengan Menggunakan Aplikasi Quickfield

Abstract

This study investigated the effect of flux spread on mitred and butted junctions in transformer cores using QuickField 6.6 Student Edition simulation application. This research focuses on understanding how different connection configurations impact magnetic field distribution and overall transformer performance. The simulation involves creating detailed geometric models of transformer cores, including mitred and butted junctions, with relevant material properties using Cold Rolled Grain Oriented (CRGO) silicon steel. The magnetic field is simulated under certain loading conditions to analyze the flux spread inside the transformer core. The results revealed an understanding of magnetic field patterns, flux concentrations, and potential losses associated with mitred and butted junctions. This study compared two types of modeling, the first testing with thermal flux then the second using the QuickField 6.6 Student Edition application. The distribution of Mitred connection flux, Flux Density (B) is 1.6921 T and Strength (H) is 336.62 A/m. As for the Butted Flux Density (B) connection of 1.1701 T and Strength (H) of 332.78 A / m. So the QuickField 6.6 Student Edition application can help researchers to see the better flux distribution of both connection types. Then it can provide transformer core geometry information and hysterical curves.
