Review on the Research Progress of Electromagnetic Metrology

On May 20, 2019, the SI actualized that the seven basic units were based on the basic physical constants, and the measurement system ushered in the major reform of “quantized unit of measurement” and “flat value transfer”. Electromagnetic metrology occupies an extremely important position in the field of metrology. It is of great significance to carry out research on electromagnetic measurement to maintain the advanced quality of value transmission and promote the new development of metrology. The basic characteristics of electromagnetic measurement were introduced, its research status in quantum standards and chips, Joule balance, AC electricity metering, AC impedance and ratio metering, high voltage metering, and magnetic parameter measurement were summarized. Finally, the development trend of electromagnetic measurement was prospected.
