Differential Measurement System based on Programmable Josephson Voltage Standards for low frequency ac voltage measurement

The paper discusses the validation of ac voltage differential measurement system based on Programmable Josephson Voltage Standards and commercial ac sources. It focuses on calibrating the fundamental effective value of low-frequency (62.5 Hz and 100 Hz) ac sine waves (0.75 Vrms). Preliminary results...

Description
Summary:The paper discusses the validation of ac voltage differential measurement system based on Programmable Josephson Voltage Standards and commercial ac sources. It focuses on calibrating the fundamental effective value of low-frequency (62.5 Hz and 100 Hz) ac sine waves (0.75 Vrms). Preliminary results show that the relative consistency and Type A uncertainty under these conditions are better than 1 part in 10 6 .
