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 .
