  • Supported by the National Science and Technology Support Program and the National Key R&D Program, the National Institute of Metrology, China (NIM), has undertaken research and established a new AC impedance traceability system based on the new generation calculable capacitor. This includes the creation of new primary standards for capacitance and inductance, as well as AC resistance standards. The new systems have enabled the precise realization of the capacitance unit "Farad" and the inductance unit "Henry", enhancing the traceability capabilities for dissipation factor standard, capacitance working standard, inductance working standard, and AC resistance standard. This work has also included revising the calibration systems for capacitance, inductance, and dissipation factor measuring instruments, as well as updating regulations and specifications for standard capacitors, standard inductors, AC resistors, capacitor boxes, inductance boxes, and AC resistance boxes. As a result, a new AC impedance traceability system for China, based on the new generation calculable capacitor, has been established.
