Dissolved gas analysis (DGA) and fourier transform infra red (FTIR) spectroscopy of thermal-aged natural ester-paper composite

2017 52nd International Universities Power Engineering Conference (UPEC), 2017
Due to environmental consideration, natural ester was developed as liquid insulation for high voltage transformer. This paper reports the Dissolved gas Analysis (DGA) and Fourier Transform Infrareed (FTIR) Spectroscopy of Thermally-Aged Natural Ester-paper composite. The sample used were natural ester from palm oil and kraft paper insulation.

Prediksi Kegagalan Transformator Daya dengan Metode DGA(Dissolved Gas Analysis) Menggunakan Random Forest Berbasis TDCG

2023
Transformers are critical components, and early detection of potential failures plays an important role in the reliable operation of the power system. This article describes a novel approach for power transformer failure prediction based on dissolved gas analysis (DGA) by applying the TDCG method with Random Forest algorithm.

Evaluasi Metode Dissolved Gas Analysis (DGA) pada Campuran Minyak Nabati dan Mineral Akibat Gangguan Partial Discharge (PD)

2023
Abstrak Minyak yang sering digunakan sebagai bahan isolasi pada transformator yaitu minyak mineral, namun beberapa dekade terakhir banyak yang mengganti minyak mineral dengan minyak nabati. Adanya gangguan thermal dan listrik pada transformator, mengakibatkan minyak isolasi mengeluarkan senyawa gas.
