Recently, the National Natural Science Foundation of China (NSFC) officially announced the results of the 2025 Major Scientific Instrument Development Projects. Led by Professor Dang Zhimin from the Department of Electrical Engineering, and jointly applied for with North China Electric Power University, the 2025 NSFC Major Scientific Instrument Development Project titled “In-situ Characterization Principles and Testing Platform for the Correlation between Micro-Regional Structure and Dielectric Properties of Composite Dielectric Materials under Multi-Field Effects” has been successfully approved.

The project focuses on the major demands of elucidating the structure–property relationships at micro-regional interfaces of polymer composite dielectrics and evaluating material performance of power equipment under operational and fault stresses. It innovatively proposes a capacitance measurement principle based on “high-order tensors,” integrates multi-physical-field coupling control technologies involving electrical, thermal, and mechanical fields, and develops a scanning probe testing platform with high-precision micro-regional characterization capabilities under complex environments. The project aims to break through key technical bottlenecks in the theory of micro–macro performance correlation of composite dielectric materials and in performance enhancement under complex operating conditions, ultimately realizing the development and empirical validation of a testing platform prototype with independent intellectual property rights.

It is reported that a total of 70 major scientific instrument projects across numerous disciplines nationwide were funded this year. This marks the first time that the Department of Electrical Engineering has been approved for an NSFC Major Scientific Instrument Development Project. Addressing the urgent demands of future low-carbon and intelligent new-type power systems for high-performance power equipment, the project is grounded in advanced characterization and analysis technologies for electrical engineering materials, and is committed to deepening fundamental theoretical understanding of key physical phenomena and laws, while providing essential original scientific instruments and core technological support.
