A new integrated design of smart transformer

The development of smart transformers meets with some issues as mismatch interfaces between mechanical parts and electrical parts, non-standard function settings in smart components and other similar problems. To solve these issues, this paper proposed an integrated design based on the theory of integrated design, elaborating the design of transformer and sensor integration as well as transformer and smart component integration. And a simulation of the leakage current at the tap of capacitive bushing under different levels of voltage was conducted at the end of this paper, providing guide for future research.
