Abstract

Isolasi minyak merupakan bagian penting dalam sebuah transformator, karena dapat melindungi, mendinginkan dan mencegah terjadinya kerusakan di dalam transformator. Akan tetapi semakin lama penggunaan transformator maka akan mengalami penuaan terhadap minyak dan isolasi kertas pada transformator tersebut sehingga tentunya akan mengalami penurunan dalam performasinya, terlebih lagi adanya pengaruh kontaminan dari isolasi kertas yang mengalami penuaan di transformator tersebut. Oleh karena itu penelitian ini berfokus terhadap pengaruh kertas isolasi terhadap kekuatan breakdown voltage pada nanofluid konduktif Fe3O4 pada transformator. Pada penelitian ini telah dilakukan pengujian yang bertujuan untuk menganalisis topik utama yang menjadi perhatian penulis seperti pengujian sedimentasi, pengujian particle size analyzer, pengujian breakdown voltage, serta pengujian partial discharge. Selain dari semua pengujian tersebut, penelitian ini juga berfokus kepada analisis gas yang terkandung didalam nanofluid Fe3O4 yang tercampur selulosa setelah diberikan gangguan partial discharge maupun breakdown voltage menggunakan dissolved gas analysis (DGA) dengan berbagai metode seperti analisis TDCG, key gas, roger ratio serta analisis duval triangle. Hasil penelitian menunjukkan bahwasanya nanofluid Fe3O4 yang tercampur dengan kertas selulosa memiliki pengaruh terhadap kekuatan Breakdown voltage dan partial discharge. Selain itu Nanofluid Fe3O4 yang tercampur dengan kertas selulosa yang telah diberikan gangguan breakdown voltage ataupun partial discharge, terdapat kandungan gas yang terlarut didalamnya. Pada penelitian ini analisis gas terlarut menggunakan metode key gas dan duval triangle dapat mengidentifikasi lebih baik dan lebih detail terhadap kandungan gas pada nanofluid Fe3O4 yang tercampur dengan kertas selulosa daripada metode dissolved gas yang lain.

Insulating oil is an important part of a transformer because it can protect, cool, and prevent damage to the transformer. However, the longer the use of the transformer, the aging of the oil and paper insulation in the transformer will certainly experience a decrease in its performance, and moreover the influence of contaminants from aging paper insulation in the transformer. Therefore this study focuses on the effect of insulating paper on the breakdown voltage strength of Fe3O4 conductive nanofluid in transformers.
In this research, tests have been carried out which aim to analyze the main topics of concern to the author such as sedimentation testing, particle size analyzer testing, breakdown voltage testing, and partial discharge testing. Apart from all these tests, this research also focuses on the analysis of the gas contained in the Fe3O4 nanofluid mixed with cellulose after partial discharge and breakdown voltage disturbances using dissolved gas analysis (DGA) with various methods such as TDCG analysis, key gas, Roger ratio, and analysis Duval triangle. The results showed that Fe3O4 nanofluid mixed with cellulose paper had an effect on breakdown voltage and partial discharge strength. In addition, Fe3O4 nanofluid mixed with cellulose paper that has been subjected to breakdown voltage or partial discharge interference has a gas content dissolved in it. In this study, dissolved gas analysis using the key gas and Duval triangle methods could identify better and in more detail the gas content of Fe3O4 nanofluid mixed with cellulose paper than other dissolved gas methods.
