Adsorption of Decomposition Gases at Overheating and Discharge Malfunctions in Gas-Insulated Transformers

Concentration in population and business activities results in high energy demand in urban areas. This requires the construction of underground substations. Oil-less, non-flammable and non-explosive equipment is recommended for underground substations. Therefore, gas-insulated transformers have been developed. Development of the method for diagnosis of gas-insulated transformers is required.

In this paper, experimental survey over the main components of decomposes generated by various faults in gas-insulated transformers is described that is carried out through simplified model tests. These results will be used to develop the diagnostics method for gas-insulated transformers.
