Investigation of winding faults of traction transformers

Cleaning of transformer oils using the electric field

“…R2 was selected as the most recent of these methods in the polymyallic method, and R2 = 0.8019 was determined for the untreated sample, and R2 = 0.8425 for the purified sample. Damak was found to have changed to R2 = 0.0406 [3][4][5]. So, the study sees that if we compare the values obtained as a result of the experiment, it turned out that the perforation voltage of the oil increased by 2.59 kV, and this is important information about the improvement of the operational characteristics of the oil.…”

Prediction of the stress - strain state of the bogie frames of shunting locomotives using the finite element method

“…The residual service life of the supporting structures of shunting locomotives is largely determined at the time of inspection by the node having the smallest residual service life E3S Web of Conferences 401, 03041 (2023) CONMECHYDRO -2023 https://doi.org/10.1051/e3sconf/202340103041 [8][9][10]. Detection of such a node is possible only with the help of modern engineering software and diagnostic devices, otherwise it becomes even easier to make a mistake due to incorrect evaluation and incorrect evaluation of all defects present during the inspection.…”

Development of a simulation model for assessing the technical condition of transformers exploited in hydroelectric stations

“…It is well known that water pressure and flow rely on the power of a hydroelectric power plant and a cascade as a whole. Hydroelectric power plants -hydroelectric power plants are the most common power plants and are a set of structures and equipment that convert the energy of water flow into electricity [3][4][5][6]. Uninterrupted supply of electricity to consumers is closely related to the reliable and continuous operation of hydroelectric power plants.…”

“…The lack of universal approaches that make it possible to obtain, on a unified methodological basis, a description of the reliability indicators of transformers depending on changes in operational factors and state parameters, makes it difficult to solve problems within the framework of this technology and limits the scope of its effective application. Determining the value of the condition of transformers makes it possible to prevent possible failures in them [3][4][5][6][7]. Modern systems based on artificial intelligence (SI) tools, such as artificial neural networks (SNT) and artificial fuzzy logic (SNM), can solve this problem due to the ability to learn input data and perform approximate calculations [7][8][9][10][11][12][13][14][15][16].…”
