Abstract

Transformator daya mempunyai peran penting pada sistem tenaga listrik. Transformator berfungsi sebagai penyalur tegangan dari pembangkit hingga ke sistem distribusi agar sampai ke konsumen. Tranformator memiliki isolasi berupa minyak transformator, selain itu berfungsi sebagai pendingin. Transformator yang memiliki beban besar, dan digunakan secara terus-menerus mengakibatkan inti transformator panas sehingga dibutuhkan minyak isolasi. Penelitian tentang pengaruh unsur-unsur gas yang terdapat pada minyak terhadap breakdown belum pernah dilakukan. Penelitian ini menyajikan informasi pengaruh antara unsur gas yang terdapat pada minyak terhadap breakdown minyak. Metode yang digunakan adalah regresi linier berganda menggunakan 300 data. Analisis hasil dari regresi berdasarkan metode statistik, dan grafik yang dihasilkan masing-masing gas terhadap breakdown. Analisis dilakukan terhadap maisng-masing gas, semua gas, kombinasi tiga gas, kombinasi empat gas tanpa asetilen, dan kombinasi tiga gas tanpa asetilen. Target dari tugas akhir ini adalah mengetahui pengaruh unsur-unsur gas terhadap breakdown minyak. Hasil dari penelitian terdapati bahwa pengaruh antara semua unsur gas pada minyak dengan breakdown minyak kecil yaitu 0.325, dengan fungsi Breakdown=0.024 Metana-0.002 Karbon Dioksida-0.016 Etilen+ 0.008 Etana-0.001 Oksigen+62.81. Diharapkan dengan adanya analisis ini dapat menjadi acuan untuk penelitian selanjutnya menggunakan metode statistik. ========================================================================================================= Power transformator has significant role in the power system. The function of transformator is to distribute voltage from generator until distribution system for consument. Tranfsormator has an insulation form oil, beside that the oil has a function as a chiller. Transformator which has a full-load and used continuously would make heat the core therefore we need the insulation oil. There is no research such an impact of gases on oil insulation for breakdown voltage yet. This research imply an information an impact of gases in insulation oil for breakdown voltage. Multiple linear regression is the method that used on this research, which use 300 data. The result of multiple linear regression analysis based on statistic method and each gases’s graphic based on breakdown voltage. Analysis has been done by each gases, three combination of gases, four combination gases without acethylene, and three combination gases without acethylene. The target of this final assignment is being able to know about an impact of gases that consist on oil transformator for the value of breakdown voltage. The result of this research is gases have 0.325 impact on breakdown voltage, which is that result is classified as a slight impact for breakdown voltage. The intention of this analysis result is be able to be reference for the future research who use statistic method.
