A fast-reversed DC voltage/current source to measure

Kampik M., Tokarski J., Barwinek W., Kurczalski M.

Measurement Automation Monitoring

2016

Vol. 62, No. 1

2--6

The paper presents a fast-reversed DC voltage/current source (FRDC) used for determination of the frequency-independent AC-DC transfer difference of thermal voltage converters. It contains also results of experiments and measurements.

RMS voltage measuring system for precise evaluation of electric quantities

Pogliano U., Trinchera B.

Metrology and Measurement Systems

2007

Vol. 14, nr 4

555-562

This paper is about a system for the measurement of RMS voltage. One or more of these systems can be employed as components for a wide range of applications for the measurement of electrical quantities in the field of electrical metrology. The first implementation has demonstrated its functionality and the possibility to reach a stability of the AC voltage measurement in a wide frequency range with an accuracy within 10 parts in 10&sup6;, limited only by the DC voltage accuracy of the DAC employed. A second implementation, now under investigation, aims at improving the accuracy of the system for high precision measurements.
