Abstract

Penelitian ini membahas mengenai peningkatan kekuatan dielektrik pada kertas kraft yang diimpregnasi minyak kedelai berpengisi campuran SiO2 dan CQD dengan konsentrasi total 0,01 wt%. Kertas kraft yang akan diuji berbentuk persegi empat dengan panjang sisi 30 mm dan ketebalan 0,08 mm. Sampel uji akan direndam menggunakan bahan pengisi SiO2 dan CQD dengan variasi waktu perendaman 24, 48, 72, 96, 120 jam, dan sampel uji lainnya direndam dengan variasi waktu perendaman yang sama tanpa diberi bahan pengisi SiO2 dan CQD sebagai pembanding (kontrol). Pengujian dilakukan menggunakan sistem elektroda jarum-piring dengan jarak sela sebesar 1 mm dengan laju kenaikan tegangan sebesar 100 V/s. Hasil pengukuran PDIV dengan pengisi SiO2-CQD pada masing-masing variasi waktu perendaman mengalami peningkatan sebesar 2,694%; 7,684%; 8,814%; 10,571%; 9,280% dibandingkan dengan tanpa pengisi. Kemudian, hasil pengukuran Vbd dengan pengisi SiO2-CQD pada masing-masing variasi waktu perendaman mengalami peningkatan sebesar 8,159%; 4,959%; 6,671%; 7,100%; 8,023% dibandingkan dengan tanpa pengisi. Hal ini menunjukkan bahwa nilai PDIV dan Vbd mengalami peningkatan ketika diberi pengisi SiO2-CQD. Ini dimungkinkan terjadi karena bahan pengisi SiO2 memiliki kestabilan dielektrik dan termal yang baik, ditingkatkan juga dengan CQD. This thesis report as result of a research with topic the improvement of dielectric strength in soybean oil-impregnated kraft paper with SiO2 and CQD fillers with concentration of 0.01 wt%. The material sample used is solid insulating kraft paper with a thickness of 0.08 mm and a size of 30 mm length and 30 mm width. Kraft paper samples were impregnated with soybean oil with SiO2-CQD filler under time variations of 24, 48, 72, 96, and 120 hours and the other one of sample were impregnated with soybean oil without SiO2-CQD filler as control sample. Using needle-plate electrodes with gap distance of 1 mm under high voltage alternating current application the partial discharge inception voltage and complete breakdown were measured. Alternating high voltage was used in the test with an increase rate of 100 V/s. The measurement result of PDIV with SiO2-CQD filler in each variation of immersion time increased by 2.694%; 7.684%; 8.814%; 10.571%; 9.280% compared without filler. Then, the measurement results of Vbd with SiO2-CQD filler in each variation of immersion time increased by 8.159%; 4.959%; 6.671%; 7.100%; 8.023% compared without filler. This shows that the PDIV and Vbd values increase when given SiO2-CQD fillers. This is possible because the SiO2 filler material has good dielectric strength and thermal stability, enhanced by CQD.
