Performance Analysis of Transformer Oil Based on Dissolved Gas Analysis (DGA) Test Results Using Total Dissolved Combustible Gas (TDCG) Method at PLTU MUARA KARANG

JREEC : Journal of Renewable Energy, Electronics and Control, 2023
Transformer is a device used to increase or decrease an AC voltage without any change in power. Not only main transformers are needed, but Auxilary transformers are very important as well. The method for identifying and analyzing gas dissolved in transformer oil is referred to as the DGA (Dissolved Gas Analysis) method. In this study, it identified the

ANALISIS KARAKTERISTIK MINYAK TRANSFORMATOR MENGGUNAKAN PENGUJIAN DISSOLVED GAS ANALYSIS (DGA) PADA IBT 1 GARDU INDUK [PDF]

Foristek, 2022
Electrical energy is an important factor to support people's lives. Electrical energy from the generator is channeled through a transmission line to the substation. Transformer (transformer) is a very important equipment in the electric power system. Inside there is oil which functions as an insulating medium and also as a cooling medium.

Gas laws for transformer dissolved gas analysis DGA starting from the ideal gas equation of state [PDF]

Transformers Magazine
Dissolved gas analysis (DGA) is a non-invasive screening and diagnostic method for liquid-insulated power transformers. The basic gas laws underlying common calculations used for DGA interpretation are derived and explained from the ideal gas equation of state.

Multiple incipient fault classification approach for enhancing the accuracy of dissolved gas analysis (DGA) [PDF]

IET Science, Measurement & Technology, 2019
Multiple incipient faults are practically known to exist in transformers. They tend to produce suddenly changing ratio limits in ratio‐based methods or oscillation of fault location in graphical methods. In consequence, the energy associated with them lies in‐between low and high severity single faults.
