Numerical Investigation of the Effects of Temperature-Dependent Permittivity and Space-Charge Transport on the Electric-Field Distribution in the Oil–Paper Insulation of an Oil-Immersed Transformer

To investigate the effects of the thermal state under rated operation and space-charge transport on the electric-field distribution in oil–paper insulation, a sequentially coupled multiphysics model is developed for a 30 kVA single-phase three-limb oil-immersed transformer. The n...

Transmission line defect detection via an integrated improved YOLOv8 and deep neural random forest framework

Abstract How to effectively identify defects in power transmission lines using unmanned aerial vehicle (UAV) technology remains a key research focus. This paper presents an optimization over traditional convolutional neural networks by proposing a spatially deformable convolution...
