- This paper describes the performance of a wideband HVDC reference divider. The divider concept is a shielded modular divider and it is intended for traceable calibration of HVDC measuring systems up to 1000 kV 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. © 2014 IEEE.

Journal article (peer-reviewed)abstract
- This paper describes the design and performance of a wideband high-voltage dc (HVDC) reference divider module. The module has a nominal voltage of 200 kV, and it has been designed so that a number of modules can be stacked to extend voltages up to 1000 kV. The module, or a stack of modules, will be 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.
