| Abstract: | The traditional calibration method of zinc oxide arrester tester is difficult to simulate the fundamental frequency resistive current, capacitive current and third-harmonic resistive current. In this paper, a low noise circuit architecture is designed. The developed reference voltage, full current generator, power amplifier circuit, feedback circuit, the standard sine wave voltage signal and current containing third harmonic are generated. After verification, the calibration device fundamental wave accuracy of voltage and current is less than 0.1%, and the third-harmonic is better than 1%, which fully meets the needs of laboratory calibration and solves the calibration problem of zinc oxide arrester tester. |
