“…Each 200 kV module consists of four 50 kV submodules. A submodule has 51 selected 10 MΩ precision film resistors with an average temperature coefficient (TC) less than (+1.1 ± 0.2) µΩ/Ω/K., and a voltage coefficient (VC) of (-10 ± 4) µΩ/Ω/kV [9]. The low TC will reduce the effect of self heating; the known VC is easy to compensate numerically.…”

This paper describes design principles of a wideband HVDC reference divider. The modular divider will be used 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.

“…The resistors in the high-voltage modules have been characterized by sample testing, using 100 sets of three resistors, rendering a temperature coefficient of (+1.1 ± 0.2) µ / /K, and voltage coefficient (VC) of (−10 ± 4) µ / /kV [14]. The low temperature coefficient reduces the effect of self-heating and the known voltage coefficient can be compensated numerically.…”

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.

“…The performance of the dividers is affected not only by the line structure and technological level, but also by the stability of the resistors [2] . Abroad some scholars sort the high voltage arm resistors to make dividers, by means of comparing the resistors made by different companies and different technological levels according to the influence degree caused by temperature and humidity change [3] . Considering economic factors, all the resistors used in the project are the high-voltage glass glaze thick film resistors [4] produced by domestic companies.…”

The stability of the high voltage arm resistors has a strong influence on the performance of the resistance high DC voltage divider. So by analyzing the main parameters that affect the resistor value change, including voltage coefficient, power coefficient and so on, a new matching method is proposed to make a high precision high DC voltage divider in this paper. Based on the principle of pairing the resistors and adjusting the big and small ones, a high precision high DC voltage divider could be made with the voltage variation less than 0.005%, even on the condition of using high voltage coefficient and power coefficient resistors.
