Abstract
This paper presents the characterization of a resistive
high-voltage dc (HVDC) reference divider and methods to
establish traceability. The divider is designed for use
as a laboratory reference for calibration of HVDC
measuring systems up to 1000 kV. Targeting a measurement
uncertainty of 20 µV/V at full voltage has put a focus on
the temperature coefficients of the resistors,
elimination of humidity dependence, and control of
leakage currents in the high-voltage arm. A scale factor
calibration against a 50 kV divider at 10 kV leads to an
expanded uncertainty of 15 µV/VV/V.
