Abstract

Pada studi ini efek feroresonansi terhadap suatu sistem kelistrikan khususnya pada Inductive Voltage Transformers (IVT) dapat disebabkan oleh switching. Fenomena ini dapat menyebabkan tegangan lebih pada IVT. Simulasi dilakukan dengan perangkat lunak ATPDraw/EMTP. Variabel yang diteliti meliputi variasi kapasitansi grading (Cg) dan shunt (Cs) serta waktu switching dengan rentang waktu 0,02 detik. Hasil simulasi memperlihatkan bahwa pada variasi kapasitansi grading (Cg) diperoleh tegangan puncak mencapai 180,74% terhadap tegangan puncak normal pada nilai Cs sebesar 0,01 uF. Pada variasi kapasitansi shunt (Cs) diperoleh tegangan puncak sebesar 764,42% pada nilai Cg sebesar 0,005 uF. Sedangkan variasi waktu switching diperoleh tegangan puncak sebesar 159,9% pada rentang waktu 0,05 detik hingga 0,06 detik saat nilai Cg dan Cs masing-masing sebesar 0,005 uF dan 0,01 uF. ========================================================================================================================================================================================== In this study the effect of feroresonance in an electrical system, especially in Inductive Voltage Transformers (IVT) can be caused by switching. This phenomenon can cause overvoltages in IVT. The simulation is done with software ATPDraw / EMTP. The variables studied include variations in grading capacitance (Cg) and shunt (Cs) as well as the switching time with a time span of 0.02 seconds. The simulation results show that the variation of grading capacitance (Cg) obtained peak voltage reaches 180.74% of the normal peak voltage at a Cs value of 0.01 uF. In the variation of shunt capacitance (Cs) obtained a peak voltage of 764.42% at a Cg value of 0.005 uF. While the switching time variation obtained peak voltage of 159.9% in the time span of 0.05 seconds to 0.06 seconds at Cg and Cs values respectively of 0.005 uF and 0.01 uF.
