Abstract
The composition and characteristics of the State primary standard of the unit of electric field strength in the frequency range, of 0–20 kHz GET 158-2020 are described. The lower limit of the frequency range for reproducing an alternating electric field, in accordance with regulatory requirements, has been expanded from 20 Hz to 5 Hz; the upper limit of the range for reproducing the electric field strength has been expanded to 4000 V/m. The NSP of the standard is 1.4 %, the zero value of the electric potential in the center of field-forming system is provided. The peculiarities of estimation of the components of the non-excluded systematic error and the error of transferring the unit of electric field strength, related to the symmetric configuration of the standard, are discussed, including those due to the interaction of measuring antennas with the electrodes of field-forming system. A draft of the State verification scheme for electric field strength measuring instruments was developed and discussed, taking into account all the trends in the development of this type of measurement.
