Abstract
Feroresonansi merupakan sebuah fenomena non-linear yang dicirikan dengan adanya overvoltage dan ketidaksesuaian bentuk gelombang akibat adanya perpaduan antara induktansi non linear dengan kapasitor. Dampak dari feroresonansi dapat bertahan hingga dalam keadaan steady state yang menyebabkan kelebihan suhu hingga menyebabkan kerusakan pada peralatan. Oleh karena itu, tujuan dari studi ini ialah untuk memahami dan mengidentifikasi fenomena feroresonansi serta membedakan dengan gangguan lainnya seperti overvoltage dan harmonisa. Pengujian feroresonansi dilakukan dalam skala laboratorium menggunakan rangkaian dasar feroresonansi yang teridiri dari kapasitor dan transformator terhubung secara seri. Selain rangkaian feroresonansi, gangguan lain yang diambil dalam studi ini ialah gangguan harmonisa akibat adanya penambahan beban lampu LED. Hasil pengujian akan diolah menggunakan transformasi wavelet dan perhitungan energi kumulatif. Adapun hasil nilai threshold yang membedakan feroresonansi dengan gangguan lainnya yaitu 9.24 J untuk transformator tipe H dan 7, 97 J untuk transformator tipe M.
=================================================================================================
Ferroresonance is a non-linear phenomenon characterized by overvoltage and waveform mismatch due to the combination of non-linear inductance with capacitors. The impact of ferroresonance can last up to a steady state which causes excess temperature to cause damage to the equipment. Therefore, the purpose of this study is to understand and identify the phenomenon of ferroresonance as well as to distinguish it from other type of wave such as overvoltage and harmonics. The ferroresonance test is performed on a laboratory scale using a basic ferroresonance circuit consisting of capacitors connected in series with transformers. In addition, another type of wave that taken in this study is harmonic wave due to the addition of LED light on the load side. The results will be processed using wavelet transformation and cummulative energy. The threshold value that distinguishes feroresonance with other type of wave are 9.24 J for the transformer type H and 7, 97 J for type M transformer.
