Diseño de una plataforma digital para detección y diagnóstico de fallas incipientes o avanzadas para transformadores de potencia, basado en el análisis de gases disueltos (DGA)

Abstract

This research exposes the analysis of the generation of gases in the tank inside the transformer because these are generated due to thermal failures, electrical failures, mechanical stress, and adverse environmental conditions, in addition to incompatibility with certain materials. For this reason, the concentration of five combustible gases hydrogen (𝐻2), methane (𝐶𝐻4), acetylene (𝐶2𝐻2), ethylene (𝐶2𝐻4), ethane (𝐶2𝐻6) produced by the decomposition of the oil is evaluated, as well as the amount of oxygen that accelerates the depolymerization of the paper producing carbon monoxide (𝐶𝑂) and carbon dioxide (𝐶𝑂2). However, the generation of gases cannot be possible without the energy necessary to break the hydrocarbon bonds, in this way the individual analysis of these gases and depending on several combinations allow to identify the nature of the failure.
