Abstract
Kemunculan ferroresonance pada suatu sistem kelistrikan
khususnya Capacitive Voltage Transformer (CVT) dapat disebabkan
oleh sambaran petir. Fenomena ini dapat menyebabkan tegangan lebih
dan arus lebih CVT. Perangkat lunak yang digunakan pada studi ini
adalah ATP/EMTP. Parameter yang diteliti meliputi variasi amplitudo
impuls petir dan durasi impuls petir yang meliputi variasi durasi waktu
muka (ts) dan waktu punggung (tr) terhadap tegangan puncak dan arus
puncak pada CVT. Dari hasil simulasi diperoleh tegangan puncak
mencapai 267,5% terhadap tegangan puncak normal dan arus puncak
mencapai 266,1% dari arus normal pada primer.

The occurrence of ferroresonance on an electrical system in
particular Capacitive Voltage Transformer ( CVT ) can be caused by a
lightning strike. This phenomenon can lead to overvoltage and
overcurrent. The software used to simulation ferroresonance is
ATP/EMTP . Parameters studied are variations of lightning impulse
amplitude and the lightning impulse duration include variations of front
time duration ( ts ) and back time duration ( tr ) to the peak voltage and
peak current in the CVT . The simulation results show that peak voltage
reached 267.5 % from normal peak voltage and the peak current reaches
266,1 % from normal current on the primary .
