DC Voltage Divider Calibration Device

DC Voltage Divider Calibration Device is composed with NRPD Series DC Standard Voltage Divider and ZGF-GW Series High Stability DC High Voltage Generator.
NRPD Series DC Standard Voltage Divider also known as high precision DC voltage divider it is developed as a standard measurement equipment for calibrating DC voltage divider (digital high voltage meter) in high voltage measurement department or high voltage testing institute or high voltage measurement company. It can be used to test the high voltage divider with accuracy of 0.2% 0.5% 1% 1.5% or lower accuracy of the electrostatic voltage meter etc. Due to its high accuracy it can measure relatively small changes in DC voltage providing a reliable measure for analyzing various materials or measuring voltages or calibrating various voltages.
ZGF-GW Series High Stability DC High Voltage Generator also known as DC Power Source it is another technical achievement of our company it is developed based on many years of experience in producing ZGF Series DC high voltage generator and fully absorbs the valuable opinions of the end users. This device is adopted the following major improvements: adopts multi-stage voltage pre-stabilization circuit high-stability low-temperature drift sampling resistor multi-link voltage feedback circuit etc. so the output voltage stability is greatly improved the voltage drift is very small and has a very low ripple coefficient. It is especially suitable for measuring and transmitting departments at all levels various provincial electric power research institutes (pilot test institutes) major zinc oxide arrester factories and voltage divider manufacturers as a high-stability test power supply when the 0.1% high-voltage DC standard is established.
