Abstract :
A system to calibrate DC voltage divider with increment taps up to 1 kV has been developed. During calibration, the divider is grounded and driving current is supplied, similarly to when used after being calibrated. Relative combined uncertainty of 1000 V/10 V was 0.1 parts per million (k = 1).
