Abstract

Studi ini meneliti pengaruh topologi pemotongan inti transformator tiga fasa yang berbeda terhadap kurva magnetisasi dan arus inrush. Topologi pemotongan inti transformator yang diteliti terdiri dari transformator yang memiliki inti dengan cara potong A yaitu tersusun dari bentuk I atau persegi panjang dan transformator yang memiliki inti dengan cara potong B yaitu tersusun dari bentuk yoke-leg-center. Penelitian pengaruh topologi pemotongan inti transformator terhadap kurva magnetisasi beserta distribusi medan magnet dilakukan melalui simulasi Finite-Element Method (FEM) pada titik-titik sambungan antarpotongan inti. Hasil dari simulasi FEM digunakan untuk mencari arus inrush masing-masing transformator. Hasil penghitungan arus inrush dari simulasi kemudian dibandingkan dengan eksperimen pengukuran arus inrush. Keberadaan fluks sisa menjadi pertimbangan dalam pengukuran arus inrush, sehingga metode demagnetisasi digunakan untuk memperoleh arus inrush yang sebenarnya. Berdasarkan hasil simulasi dan eksperimen diperoleh bahwa topologi pemotongan inti transformator dapat berpengaruh pada kurva magnetisasi dan arus inrush. Ini dibuktikan dengan perbedaan kurva magnetisasi dan arus inrush kedua topologi pemotongan inti transformator. ===================================================================================================== This study observes core cutting topology of three phase transformer effect on magnetization curve and inrush current. The studied topologies consist of core cutting A which is made up by letter I form or rectangular and core cutting B which is made up by yoke-legcenter. The study of core cutting topology effect on magnetization curve and megnetic field is done is researched by Finite-Element Method (FEM) simulation at the points of connection between the core pieces. The results of FEM simulation, then, is used to find inrush current of each transformer. Inrush current results of the simulation are compared to experimental measurements of inrush currents. The existence of residual flux or remanent flux is considered in inrush current measurement, so demagnetization method used to obtain the real inrush current value. Based on simulation and experimental results obtained that the topology of the transformer core cutting can affect the magnetization curves and inrush currents. These are proven by differences in the magnetization curve and inrush current of both topology transformer core cutting.
