The problem of safe operation of the transformer is prominent, and only by comprehensively, timely and accurately sensing and mastering the key parameters inside the transformer can the internal state of the transformer be judged and accidents prevented. How to measure the spatial-temporal distribution of internal multiphysics in high voltage, strong magnetic field, and high temperature environment is a challenge.

Research experience: 1) refine the research objectives from the field needs, and develop sensors with comprehensive and balanced performance; 2) start from the bottom as much as possible to solve the special needs of power grid equipment sensing; 3) multi-disciplinary cross-integration, actively learn knowledge in other fields; 4) carry out the teaching of basic optical courses, teaching each other; 5) strengthen school-enterprise cooperation and accelerate the landing of results.
