Calculating a Health Index for Power Transformers Using a Subsystem-Based GRNN Approach
IEEE Transactions on Power Delivery, 2018A power transformer is one of the most crucial items of equipment in the electricity supply chain. The reliability of this valuable asset is strongly dependent on the condition of its subsystems such as insulation, core, windings, bushings and tap ...

Study of Analysis and Experiment for Ability to Withstand DC Bias in Power Transformers
IEEE transactions on magnetics, 2018DC bias in power transformers leads to strong core saturation and thus nonlinearly inferior operation. This paper analyzes the ability of power transformers to withstand the dc bias by novel analytical criteria.

Chain of Thought Empowers Transformers to Solve Inherently Serial Problems
International Conference on Learning RepresentationsInstructing the model to generate a sequence of intermediate steps, a.k.a., a chain of thought (CoT), is a highly effective method to improve the accuracy of large language models (LLMs) on arithmetics and symbolic reasoning tasks. However, the mechanism
