Reliability Assessment and Maintenance Optimization of Oil-Immersed Transformers in Windblown Sand and Alpine Regions: A Bayesian Copula–Mixture Weibull Framework

High-voltage oil-immersed transformers operating in windblown sand and alpine regions are exposed to multiple environmental and operational stresses that may affect their degradation and reliability. To address limitations associated with single-distribution lifetime modeling, independent component assumptions, static...
