Research of a high voltage and high value resistors standard device

Abstract

With the continuous increase of voltage class and the rapid development of electrical equipment, we need to design a new kind of intelligent high voltage and high value resistors standard metering device which can be used to a much larger range to complete daily verification work. Based on MSP430 single-chip microcomputer, this paper designed the temperature and humidity control module and the high voltage measurement module that the measuring range can be automatically switched. By using this standard device, the measurement of voltage and resistance can reach separately to 10 kV and 200GΩ. At last by measuring the voltages and resistances and testing the temperature and humidity control system, it has indicated that the high voltage and high value resistors standard metering device in this paper meets the requirements.
