Abstract
This paper describes the design and performance of a
modular wideband high-voltage dc (HVDC) reference divider
with a ratio uncertainty of less than 0.005% at 1000 kV.
The divider has a maximum nominal voltage of 1000 kV when
five 200-kV modules are stacked on top of each other. The
divider is used for traceable calibration of HVDC
measuring systems in
customers' laboratories. The first priority in the design
was the accuracy of HVDC measurements. In addition, the
divider was designed to have wide bandwidth, both to
enable measurement of ripple voltages and to prevent
damage during possible flashovers.
