In the morning of November 24, Guangdong Electrical Industry Association held a scientific and technological achievement evaluation meeting on the "Research and development and industrialization of non-contact Rapid Calibration current and voltage integrated electronic transformer" project implemented by Chuangyin Technology Group. Many experts from China Electrical Appliances Research Institute Co., LTD., South China University of Technology, Guangzhou University, Guangdong Machinery Research Institute, Guangdong Power Grid Co., LTD. Metrology center, Guangzhou Giant Industrial Co., LTD., etc., carefully listened to the project results report and discussed the research after unanimously approved the project results appraisal, and said that the overall project technology reached the international advanced level.

By studying low-power coil sensing, non-contact high-voltage electric field coupling and sensing, rapid calibration, active temperature compensation and other technologies, this project has developed a non-contact rapid calibration current and voltage integrated electronic transformer with fast calibration, compensation and low power consumption. It has the characteristics of reliable measurement, high integration, convenient installation and low cost. Meet the intelligent development needs of the power industry.

China Science Journal, China News Network, Guangdong Science and Technology News, and Today's First article, reported the appraisal meeting in detail.
