A New Testing Method for the Dielectric Response of Oil-Immersed Transformer
IEEE Transactions on Industrial Electronics, 2020 Oil-immersed transformer is one of the most important electrical equipment in power distribution and transmission systems. Dielectric response method is a well-recognized method to diagnose the insulation defect of oil-immersed transformers. However, the applicability of this method is restricted due to the long testing time.

Study on the Deformation of the Oil-Immersed Transformer Tank by FEA
Advanced Materials Research, 2011 The oil-immersed transformer tank is an outside package component of the transformer body. The sealing quality and mechanical strength of the oil tank are affected by the deformation after loading. In this paper, the 3D finite element model of oil-immersed transformer tank is established. The oil-immersed transformer tank deformation is obtained by FEA
