Duval Triangle-Based Dissolved Gas Analysis Using GNU Octave for Transformer Fault Detection

open access: yesAvitec
Transformers are vital components in electrical power systems. However, they are also susceptible to various types of failures, including thermal and electrical faults caused by the formation of electromotive force, which, if left unaddressed, may result

Modification of Duval Triangle for Diagnostic Transformer Fault Through a Procedure of Dissolved Gases Analysis

open access: yesTransactions on Environment and Electrical Engineering, 2016
Dissolved gas-in-oil analysis (DGA) is a sensitive and reliable technique for the detection of incipient fault condition within oil-immersed transformers. When the mineral oil is subjected to high thermal or/and electrical stresses, it decomposes and, as a result, gases are generated.

Analysis of Transformer Conditions Using Triangle Duval Method

open access: yesIOP Conference Series: Materials Science and Engineering, 2018
Abstract Electrical or thermal failure that occurred in the transformer oil can produce a dangerous gas called gas fault. By indicating the content of dissolved gases in the transformer oil, can be obtained information about what happened to the oil so it can be estimated indication of the type and cause of the failure in the transformer.
