Abstract :
This paper presents a new method of calibrating de voltage ratios from 20 V: 10 V to 1000 V: 10 V. A new battery-powered differential voltage detector has been developed to reduce the uncertainty of the measurement system. An absolute self-calibration process was used and traceability to a voltage ratio standard is not necessary. The uncertainties of dc voltage ratios (20 V to 1000 V): 10 V were less than 2 × 10-7
