Title: | The transfer voltage standard for calibration outside of a laboratory | Authors: | Urekar, Marjan Gazivoda N. |
Issue Date: | 1-Jan-2017 | Journal: | Serbian Journal of Electrical Engineering | Abstract: | The transfer voltage standard is designed for transferring the analog voltage from a calibrator to the process control workstation for multi-electrode electrolysis process in a plating plant. Transfer voltage standard is based on polypropylene capacitors and operational amplifiers with tera-ohm range input resistance needed for capacitor self-discharging effect cancellation. Dielectric absorption effect is described. An instrument for comparison of reference and control voltages is devised, based on precise window comparator. Detailed description of the main task is given, including constraints, theoretical and practical solutions. Procedure for usage of the standard outside of a laboratory conditions is explained. Comparison of expected and realized standard characteristics is given. | URI: | https://open.uns.ac.rs/handle/123456789/3539 | ISSN: | 14514869 | DOI: | 10.2298/SJEE1701099U |
