Abstract
The article presents an analysis of the state of metrological support in the field of alternating electric voltage measurements in the frequency range up to 30 MHz.
The purpose of the work is to determine the required accuracy level for the further creation of secondary and working standards used in transferring the unit.
Analysis of data from the Federal Information Fund for Ensuring the Uniformity of Measurements allowed systematization of key issues of the reference base, in particular, the difficulties of ensuring metrological traceability in the frequency range up to 30 MHz. The study examines issues of improving metrological support and formulates recommendations for ensuring the required accuracy of working standards and modernizing secondary standards. The research results, presented in tables and diagrams, made it possible to assess the current state of AC voltage unit reproduction and ensure the level of preservation of the hierarchy of the State verification schedule in the medium term for 5–10 years. The findings are of practical value for standardization and metrology centers, developers of measuring instruments, specialists in the field of verification and certification of secondary and working standards. The presented information may serve as a basis for the development and implementation of new serial high-precision measuring instruments by instrumentation enterprises and gives an idea of the potential for metrological equipment of various economic sectors with them.
