Transformer insulation oil is an important liquid for insulating and cooling of transformers. For many years' mineral oil has been used for as an insulating liquid in high voltage transformer. Mineral oil has good dielectric properties, however, due to environmental problem; recently many researchers have been looking for an alternative insulating ...

Dissolved gas analysis (DGA) of natural ester insulating fluids with different chemical compositions
IEEE Transactions on Dielectrics and Electrical Insulation, 2014This study presents experimental results of the application of the dissolved gas-inoil analysis (DGA) technique to natural ester insulating fluids. The investigations covered two common types of transformer faults, discharge and overheating, and four different commercial insulating oils, one mineral and three natural esters: Biovolt A (from corn oil ...

The general problem of operational power transformer was appearing in both thermal and electrical failure. Most of the power transformer usually used insulator oil that was functioning as cooler and to dissolve its hazardous gas in order not to circulate independently.

2017 International Symposium on Electronics and Smart Devices (ISESD), 2017
This paper proposes the implementation of A3S information fusion algorithm to interpret Dissolved Gas Analysis (DGA) based on Doernenburg Ratio. A3S (Arwin-Adang-Aciek- Sembiring) is a method of information fusion derived from Bayesian Inference Method (BIM) to handle multi-hypothesis multi-indication problem for single observation time.

Electrical Network Systems and Sources, 2023
Semakin meningkatnya angka permintaan energi listrik, maka semakin meningkat juga kinerja peralatan yang berada di pembangkit listrik. Trafo memiliki isolasi di dalamnya dalam bentuk kertas selulosa dan minyak trafo. Untuk mengetahui indikasi kegagalan pada trafo, kita dapat menguji salah satu jenis isolasi pada trafo yaitu minyak trafo, dengan ...

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.

2018 IEEE PES/IAS PowerAfrica, 2018
Power transformers are an integral part of transmission and distribution plant and are often characterised by long procurements lead-times as they usually cannot be bought off-the-shelf. The procurement and replacement of a power transformer may require processes of transformer design specification, tendering, bid evaluation, contract award, designing,

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.
