Abstract
Gangguan sistem tenaga listrik seperti gangguan switching dalam sistem transmisi dapat menyebabkan timbulnya fenomena feroresonansi. Feroresonansi atau yang biasa disebut dengan resonansi non-linier yaitu suatu fenomena sistem kelistrikan yang terjadi pada kapasitor dan induktor non-linier feromagnetik. Gangguan yang digunakan terjadi pada sistem tranmisi yaitu pada Capacitor Voltage Transformator (CVT). Penanganan yang tepat berupa pendeteksian, identifikasi, pencegahan dan proteksi dibutuhkan untuk mengatasi gangguan ini. Pada studi ini digunakan metode penambahan reaktor ganda pada sisi primer CVT untuk melakukan pencegahan feroresonansi. Reaktor ganda yang dipakai dalam pencegahan ini yaitu suatu switch yang dipasang paralel dengan sebuah induktor. Hasil simulasi menunjukkan bahwa feroresonansi dapat dicegah dengan memasukan nilai 0.5 s pada Tswitch dan 141.3 mH pada induktor. Hasil analisa dari penelitian Tugas Akhir ini dapat menunjukkan kinerja penambahan reaktor ganda pada CVT untuk dibandingkan dengan metode-metode yang berbeda.

The occurrence of power system electricity fault such as switching in tranmission system causes existing of ferroresonance phenomenon. Ferroresonance or can be called non-linier resonance is an electrical system phenomenon that occurs in capacitors and ferromagnetic non-linier inductor. In this study the occurrence of fault in transmission system assumed in Capacitive Voltage Transformer (CVT). Right treatment such as detection, identification, prevention and protection is needed to solve this problem. In this study, using a methods by adding a dual reactor to the primary side of the CVT to prevent ferroresonance. Dual reactor used in this prevention is a switch that is installed in parallel with an inductor. The simulation results show thatb ferroresonance can prevented by entering a value of 0.5 s on Tswitch and 141.3 mH at inductor. The results of the analysis of this thesis can show performance of this methods dual reactor addition on CVT compared with different methods.
