Abstract

Pada penelitian ini melakukan simulasi transien untuk mengetahui kinerja metal oxide varistor lightning arrester dengan memodelkan saluran distribusi dengan model Bergeron, model PI, model Jmarti, dan model Semlyen. Simulasi transien dilakukan menggunakan software ATP Draw dengan pemberian arus impuls petir 1kA, 2,5kA, 5kA, 10kA, dan 20kA di arrester 2, arrester 3, arrester 4, dan arrester 5. Setelah melakukan simulasi kemudian membuat trend kV peak dan disipasi energi lalu menganalisis hasilnya. Hasil simulasi menunjukkan Tegangan surja pada model Bergeron dan Jmarti memiliki trend naik namun pada trend tegangan surja model PI dan model Semlyen terdapat penurunan. Penurunan tegangan surja pada model PI terjadi di arrester 2, arrester 3, dan arrester 4. Trend arus surja model Bergeron, model Jmarti, dan model Semlyen mengalami kenaikkan namun pada model PI terdapat penurunan trend arus surja. Penurunan arus surja pada model PI terjadi di arrester 3 saat pemberian arus impuls 5kA. Energi surja pada model Bergeron, model Jmarti, dan model Semlyen memiliki trend naik namun pada model PI terdapat penurunan trend energi surja. Penurunan trend energi surja pada model PI terjadi di arrester 2, arrester 3, dan arrester 4. Model Bergeron dan model Jmarti memiliki trend tegangan surja, arus surja, dan energi surja yang naik. Meski kedua model memiliki trend naik, namun model Bergeron memiliki nilai tegangan surja, arus surja, dan energi surja yang lebih besar dari model Jmarti. Dengan menggunakan trend tegangan surja, arus surja, dan energi surja yang selalu naik serta saluran yang dibumikan secara efektif maka model Jmarti adalah model terbaik yang dapat digunakan untuk memodelkan kinerja lightning arrester

In this study, transient simulations were conducted to assess the performance of metal oxide varistor lightning arresters by modeling distribution channels using the Bergeron, PI, Jmarti, and Semlyen models. Transient simulations were carried out using ATP Draw software with impulse lightning currents of 1kA, 2.5kA, 5kA, 10kA, and 20kA applied to arresters 2, 3, 4, and 5. After conducting the simulations, trends of peak voltage and energy dissipation were analyzed. The simulation results indicate that the surge voltage in the Bergeron and Jmarti models exhibited an increasing trend, while the PI and Semlyen models showed a decrease in surge voltage trend. The decrease in surge voltage was observed in arresters 2, 3, and 4 in the PI model. The surge current trends in the Bergeron, Jmarti, and Semlyen models experienced
an increase, while the PI model showed a decrease in surge current trend. The decrease in surge current occurred in arrester 3 when applying a 5kA impulse current. The surge energy trends in the Bergeron, Jmarti, and Semlyen models showed an increasing trend, while the PI model exhibited a decrease in surge energy trend. The decrease in surge energy trend occurred in arresters 2, 3, and 4 in the PI model. The Bergeron and Jmarti models exhibited increasing trends in surge voltage, surge current, and surge energy. Although both models exhibited increasing trends, the Bergeron model had higher values of surge voltage, surge current, and surge energy compared to the Jmarti model. Considering the consistently increasing trends in surge voltage, surge current, and surge energy, as well as effective channel grounding, the Jmarti model is considered the best model for modeling lightning arrester performance
