Abstract
In connection with the planned comparisons of AC and DC voltage standards based on the quantum Josephson effect by the International Bureau of Weights and Measures in accordance with the Technical Protocol of Comparisons BIPM.EM-K10, the possibility of a programmable Josephson voltage array from the State Primary Standard of the Unit of Electric Voltage GET 13-2023 for measuring sinusoidal voltages of 0.75 V and 7 V in the frequency range of 62.5–1000.0 Hz was investigated. When measuring voltages in the frequency range of 62.5–200.0 Hz, a digital voltmeter with specially developed software for measuring AC voltage was used together with the quantum voltage standard. The obtained results differ from the measurement results presented in the Technical Protocol of Comparisons. However, the results of the conducted study confirmed the possibility of using a quantum voltage standard based on a programmable Josephson array from GET 13-2023 for comparisons based on the specified Technical Protocol. The interaction of the quantum voltage standard and the AC voltage source was analyzed, and a conclusion was made on the need to control the reproduced AC voltage with a digital voltmeter with the software recommended in the Technical Protocol for comparisons.
