Abstract
Peran CVT dalam sistem kelistrikan sangat vital, terutama untuk
sistem pengaman dan pengukuran. Akan tetapi rangkaian pada CVT dapat
menimbulkan feroresonansi. Fenomena ini dapat menyebabkan tegangan
lebih dan arus lebih pada CVT. Dalam studi ini dilakukan mitigasi
feroresonansi dengan FSC pasif. Perangkat lunak yang digunakan pada
studi ini adalah ATP/EMTP. Parameter FSC pasif diteliti untuk
mendapatkan nilai yang tepat. Dari hasil simulasi didapatkan nilai Rr = 12
Ohm dan Rn = 1000 Ohm pada FSC pasif. Selanjutnya FSC pasif diuji
dengan perubahan beban CVT. Beban R dan L divarasi untuk
mendapatkan perbandingan nilai tegangan dan arus sebelum serta sesudah
dipasang FSC pasif. Dari hasil simulasi diperoleh kinerja dari FSC pasif
dapat memitigasi feroresonansi dengan baik untuk setiap nilai beban yang
diuji

The role of Capacitive Voltage Transformer (CVT) in the power
system is vital, especially for protection system and measuring. But the
circuits in the CVT can cause a ferroresonance. This phenomenon leads
to overvoltage and overcurrent in CVT. This paper presents a study of
ferroresonance mitigation using passive Ferroresonance Suppression
Circuit (FSC). The software that being used in the study is ATP/EMTP.
the Parameter of passive FSC is studied to get the right value. Simulation
results show that Rr = 12 ohm and Rn = 1000 ohm in passive FSC.
Furthermore, the passive FSC is tested with CVT load changes. The
resistive and inductive loads are be varied to obtain comparative voltage
and current value before and after the passive FSC is placed. Simulation
results show that passive FSC can effectively mitigate the ferroresonance
for each tested value load
