Abstract
Feroresonansi merupakan fenomena yang muncul karena dipicu oleh sebuah kejadian transien seperti switching, sambaran petir, atau gangguan hubung singkat, kemudian menghasilkan bentuk tegangan dan arus lebih yang abnormal dikarenakan dalam suatu sistem terdapat komponen induktansi non-linier (L) serta memiliki komponen resistansi (R) dan kapasitansi (C) konstan. Pada studi ini dibuat desain dan implementasi modul pengujian feroresonansi pada transformator 3 fasa tegangan rendah untuk dapat dianalisis secara fisis fenomena feroresonansi skala kecil berdasarkan kondisi pada sistem/lapangan. Hasil pengujian menunjukkan bahwa desain modul pengujian yang dibuat dapat berfungsi dengan baik. Modul pengujian tersebut dapat menghasilkan respon feroresonansi pada transformator 3 fasa dengan inti H dan M. Inti H dan M merupakan jenis inti besi dari transformator yang digunakan pada studi ini. Pengujian dilakukan dengan menaikkan tegangan power supply hingga mencapai rating tegangan transformator lalu memvariasikan pelepasan fasa dan nilai kapasitor hingga memunculkan respon feroresonansi. Adapun variasi pelepasan fasa yang dilakukan adalah dengan pelepasan 1 fasa dan 2 fasa. Sedangkan, untuk variasi nilai kapasitor dengan menggunakan kapasitor 10 μF, 20 μF, dan 30 μF berkonfigurasi seri dan seri-paralel. Respon feroresonansi gelombang tegangan yang diperoleh pada konfigurasi seri-paralel menghasilkan gelombang yang lebih terdistorsi dibandingkan konfigurasi seri.
==========================================================
Ferroresonance is a phenomenon that appears when triggered by a transient event such as a switching, lightning strike, or short circuit interruption, afterward shows an abnormal form of overvoltages and overcurrents because there are non-linear inductance components (L) with resistance (R) and capacitance (C) as constant components in the system. In this study, a design and implementation of the ferroresonance testing module has been made on a low voltage 3 phases transformer to produce ferroresonance based on the conditions in the real system/field. The result of the test showed that the design of the test module on the low voltage 3 phase transformer could be functioned properly. The test module can produce ferroresonance response on 3 phase transformers with H and M cores. H and M cores are the types of iron core of the transformer used in this study. The tests were carried out by increasing the power supply voltage until it reaches the transformer voltage rating and by varying the phase release of the system and the capacitor value to show up the ferroresonance response. The variation of phase release is done by releasing 1 phase and 2 phases. Meanwhile, the variations for the value of capacitors is done by using 10 μF, 20 μF, and 30 μF capacitors in series and series-parallel configurations. The response of the ferroresonance voltage wave obtained in the series-parallel configuration produces waves that are more distorted than the series configuration.
