Abstract
Pada studi ini dilakukan analisis karakteristik busur api listrik seri DC. Percobaan busur api listrik seri dilakukan dengan menggunakan variasi impedansi kabel dan variasi celah elektroda dengan nilai daya PV yang bervariasi. Panjang kabel digunakan sebesar 25 meter dan 50 meter. Sedangkan pada variasi celah yaitu 0,04 mm; 0,06 mm; dan 0,08 mm. Pada saat busur api listrik terjadi, didapatkan data arus busur api listrik, tegangan busur api listrik dan tegangan PV. Pada variasi impedansi kabel dari data arus dan tegangan yang telah diolah, didapatkan nilai arus busur, tegangan busur, resistansi busur dan daya busur. Pada variasi celah elektroda, didapatkan nilai dari durasi busur dan daya busur. Selain itu fenomena busur api listrik DC juga dianalisa menggunakan metode Pulse Sequence Analysis (PSA) untuk mengetahui pattern pola titik ketika kondisi normal dan kondisi busur. Pengolahan metode Pulse Sequence Analysis (PSA) menghasilkan pola PSA ketika kondisi normal plot titik dari pengolahan PSA tidak ada persebaran titik magnitude dengan pola yang mengarah ke kondisi ∆i mendekati 0. Hal ini disebabkan karena pada kondisi arus normal, gelombang arus cenderung konstan. Sedangkan, pola PSA pada kondisi busur api listrik yang didapatkan bahwa ketika dalam kondisi busur api listrik menghasilkan sebaran pada ΔI. Hal ini disebabkan karena pada kondisi busur api listrik terdapat penurunan gelombang arus ketika terjadi busur api sehingga persebaran magnitude lebih banyak yang merupakan tanda terjadinya busur api listrik. Dari penelitian ini diperoleh hasil penurunan nilai arus busur, kenaikan tegangan busur, kenaikan resistansi busur dan kenaikan daya busur pada setiap percobaannya pada variasi impedansi kabel. Pada variasi celah elektroda, hasil yang didapatkan semakin besar celah maka durasi busur dan daya busur berturut-turut semakin lama dan besar

In this study, an analysis of the characteristics of DC series electric arcs was carried out. Series electric arc experiments were carried out using variations in cable impedance and variations in electrode gap with varying PV power values. The cable lengths used are 25 meters and 50 meters. Meanwhile, the gap variation is 0.04 mm; 0.06mm; and 0.08mm. When an electric arc occurs, data is obtained on the electric arc current, electric arc voltage and PV voltage. By varying the cable impedance from the processed current and voltage data, the values for arc current, arc voltage, arc resistance and arc power are obtained. By varying the electrode gap, values for arc duration and arc power are obtained. Apart from that, the phenomenon of DC electric arcs was also analyzed using the Pulse Sequence Analysis (PSA) method to determine the pattern of dots under normal conditions and arc conditions. Pulse Sequence Analysis (PSA) method processing produces a PSA pattern when under normal conditions the point plot of PSA processing does not have a distribution of magnitude points with a pattern that leads to conditions where ∆i is close to 0. This is because under normal current conditions, the current wave tends to be constant. Meanwhile, the PSA pattern in electric arc conditions shows that when in electric arc conditions it produces a distribution in ΔI. This is because in electric arc conditions there is a decrease in the current wave when an arc occurs so that the magnitude distribution is greater which is a sign of an electric arc. From this research, the results obtained were a decrease in arc current values, an increase in arc voltage, an increase in arc resistance and an increase in arc power in each experiment with variations in cable impedance. In varying the electrode gap, the results obtained are that the larger the gap, the longer and greater the arc duration and arc power respectively
