Abstract
Semakin meningkatnya permintaan listrik juga akan membuat semakin terbukanya peluang usaha dalam bidang kelistrikan, salah satu peluang usaha adalah pembuat transformator. Dalam proses produksi transformator tentunya harus dilakukan pengujian transformator oleh produsen. Rentang waktu antara perendaman isolasi kertas dan pengujian harus diperhatikan agar saat dilakukan pengujian isolasi yang terdapat didalam transformator sudah dalam keadaan yang stabil. Sebelum dilakukan pengujian isolasi kertas, kertas akan diperlakukan secara berbeda-beda mulai tanpa perendaman hingga 72 jam perendaman didalam minyak dengan suhu ruang pada tiap jenis isolasi kertas. Pengujian breakdown voltage pada penelitian ini menggunakan elektroda mushroom dengan standart IEC 60156. Dari hasil pengujian didapatkan isolasi tiap jenis kertas memiliki nilai breakdown voltage yang stabil dengan lama perendaman kertas yang berbeda, kertas press 48 jam, kertas krep dan pressboard 36 jam, dan kertas kraft 12 jam. Semakin lama direndam isolasi kertas akan mengalami proses adhesi yang membuat rongga kertas membentuk susunan komposit yang lebih sempurna. Selain dilakukan pengujian breakdown voltage, akan dilakukan juga pengujian tentang kadar selulosa. Dalam pengujian selulosa didapatkan bahwa, dalam melakukan perendaman minyak akan membuat kadar selulosa dalam kertas semakin tinggi yang menyebabkan nilai breakdown voltage dari isolasi kertas akan semakin tinggi juga. ============ The increasing demand for electricity also make the opportunities business in the electricity scope, one business opportunity is the producer of transformers. In the production process of transformer, be must done by transformer testing electricity. Time span between paper insulation immersion and testing, shall be noticed when the insulation testing contained within the transformer is a steady state breakdown voltage. Prior the paper insulation testing, the paper will be treated differently without immersion until 72 hours immersion in the oil at room temperature on each type of paper insulation. Testing breakdown voltage this research using mushroom electrode standard IEC 60156. In the test results obtained isolation each type of paper has a steady state breakdown voltage value with different paper immersion period, 48 hours for press paper, 36 hours for crepe and pressboard paper, and 12 hours for craft paper. Longer of time immersion paper insulation witness a process adhesion that makes the paper cavity form more perfect composite arrangement, furthermore also be tested about cellulose content. In cellulose content testing, are found those oil immersion became increase of cellulose content in paper insulation, which causing the breakdown voltage value of the paper insulation be higher as well.
