Kolmogorov–Arnold Network in the Fault Diagnosis of Oil-Immersed Power Transformers [PDF]

open access: yesSensors
Instabilities in energy supply caused by equipment failures, particularly in power transformers, can significantly impact efficiency and lead to shutdowns, which can affect the population. To address this, researchers have developed fault diagnosis strategies for oil-immersed power transformers using dissolved gas analysis (DGA) to enhance reliability ...

Numerical Computation of the Vibroacoustic Behaviour of an Oil-Immersed Power Transformer

open access: yesJournal of Energy : Energija, 2022
This paper presents a numerical calculation method that allows for the simulation of the mechanical and acoustic behaviour of a transformer tank. In order to simulate the vibroacoustic behaviour of an oil-immersed power transformer, an acoustic-mechanical coupled three-dimensional finite-element method model of a transformer was setup.
