Research on Optimizing the Stability of Impulse Voltage Calibrator used in Traceability

Impulse Voltage Calibrator is important equipment in traceability of impulse voltage measurement. The characteristic of impulse voltage calibrator directly affects the accuracy and reliability of impulse voltage measurement. The output voltage parameters of standard calibrator will be changed after long-term operation. In order to optimize the stability and reduce the temperature rise of the calibrator, constant temperature control scheme of impulse calibrator is proposed. The parameters of (1.56/60) μs calibrator were selected to study. The results show that the long-term stability parameters of the standard impulse voltage source are improved by 0.04% and the accuracy of impulse voltage traceability is effectively improved after temperature control of the temperature.
