Abstract

Pada studi ini dilakukan estimasi fluks sisa pada transformator 1-fasa 1 kVA dengan perbedaan model pemotongan inti transformator. Metode yang digunakan adalah pemodelan transformator 1-fasa dua belitan menggunakan simulink pada perangkat lunak MATLAB. Fluks sisa dapat diestimasi menggunakan hasil dari arus inrush yang didapat saat simulasi menggunakan perangkat lunak MATLAB dan saat ekperimen pengukuran arus inrush secara langsung dengan meng-energize transformator. Setelah terlihat hasil arus inrush dari simulasi dan eksperimen langsung, maka akan didapatkan perbedaan arus inrush hasil simulasi dan eksperimen. Perbedaan tersebut digunakan untuk mengestimasi fluks sisa pada transformator 1-fasa. Hasil yang didapatkan pada eksperimen langsung dan simulasi adalah besar nilai arus inrush pada transformator E-I saat simulasi sebesar 5 A sedangkan saat eksperimen langsung nilainya 22 A ketika transformator tidak didemagnetisasi sama sekali dan memiliki nilai fluks sisa sebesar 890 Wb. Untuk transformator E/E nilai arus inrush saat simulasi sebesar 4,4 A sedangkan saat ekperimen langsung nilainya 9,7 A ketika transformator tidak didemagnetisasi sama sekali dan memiliki nilai fluks sisa sebesar 300 Wb. Estimasi nilai fluks sisa pada transformator E-I lebih besar dari pada transformator E/E pada kondisi waktu demagnetisasi yang sama. Nilai arus inrush transformator E-I juga lebih besar dari transformator E/E dipengaruhi oleh pemodelan inti. ================================================================================================================== This study deals with the estimation of residual flux in 1 kVA single phase transformer with core cutting model differences. The used method is two winding single phase transformer simulated with Simulink in MATLAB software. Residual flux can be estimated with inrush current in MATLAB software simulation result and with directly experiment inrush current measurement at energizing transformer. Having seen the result of inrush current from simulation and experiment, the result shown a difference between the simulated inrush current result and experimental result, These differences are used to estimate residual flux from 1-phase transformers. The result obtained from experiment and simulation is inrush current value from E-I transformer when simulation as much as 5 A but from the experiment as much as 22 A when demagnetization from transformer not performed and has residual flux as much as 890 Wb. And inrush current value from E/E transformer when simulation as much as 4,4 A but from the experiment as much as 9,7 A when demagnetization from transformer not performed and has residual flux as much as 300 Wb. Residual flux estimation from E-I transformer bigger than E/E transformer at the same time demagnetization. The inrush current value from E-I transformer bigger than E/E transformer. The result shows that different core cutting topology affects the residual flux as well as the time of demagnetization.
