Analysis of 132kV/33kV 15MVA power transformer dissolved gas using transport-X Kelman Kit through Duval's triangle and Roger's Ratio prediction

2018 IEEE International Conference on Industrial Technology (ICIT), 2018
In this article dissolved gas in 132kV/33kV 15MVA power transformer is analyzed using the Kelman Kit (Transport-X) through Duval's triangle method and Roger's Ratio method. Under the impact of electrical, thermal and environmental stresses, the equality of mineral insulation oil deteriorates in a gradual manner, electrical failures such as hot spots ...

Comparative Study of Duval Triangle with the New DGA Interpretation Scheme

2018
Fault diagnosis of power transformer for condition evaluation is being carried out by oil analysis for decades. The most efficient and easy way of condition evaluation of transformer is by evaluating the concentration of gases present in the transformer oil, done using dissolved gas analysis (DGA) over which several techniques are employed to predict ...

METODE RANDOM FOREST UNTUK KLASIFIKASI KERUSAKAN TRANSFORMATOR DAYA BERDASARKAN GAS TERLARUT PADA DUVAL TRIANGLE DAN DUVAL PENTAGON

JATI (Jurnal Mahasiswa Teknik Informatika)
Penyaluran energi listrik merupakan hal yang essensial dalam operasional komponen elektronik. Kinerja transformator untuk memenuhi kebutuhan transmisi bergantung pada sistem isolasi. Sistem isolasi berupa minyak transformator akan mengalami degradasi kualitas seiring dengan periode pemanfaatan alat.

The duval triangle for load tap changers, non-mineral oils and low temperature faults in transformers

IEEE Electrical Insulation Magazine, 2008
New versions of the Duval triangle for equipment filled with mineral oil are proposed for load tap changers of the oil type, equipment filled with non- mineral oils, and for low-temperature faults where stray gassing of oils may interfere with diagnostics.

Perbandingan Metode Roger's Ratio dan Metode Duval's Triangle Terhadap Kegagalan Transformator

Kualitas minyak transformator dapat diketahui dengan Dissolved Gas Analysis (DGA). Berdasarkan penelitian sebelumnya metode yang lebih unggul dalam menjawab kegagalan yang terjadi pada transformator adalah metode Roger’s Ratio dan Duval’s Triangle. Pada penelitian ini dilakukan perbandingan keefektifan dari kedua metode tersebut.
