摘　　要：为了保证氧化锌避雷器(metal oxide arrester,MOA)测试仪量值的准确可靠,需定期对其进行校准和不确定度评定。在简要阐述MOA特性及测试方法的基础上,介绍了MOA测试仪的标准信号发生器法校准方法,详细分析和评定了MOA测试仪校准结果的不确定度,通过采用传递比较法与国家高电压计量站提供的校准结果进行比对,验证了校准结果的可信度和不确定度的合理性。为MOA测试仪的校准和不确定度评定提供了方法,有助于提高MOA测试仪量值传递的准确性和一致性。In order to ensure the accuracy and reliability of the measurement value of the metal oxide arrester （MOA） tester, it is necessary to calibrate it and evaluate its uncertainty regularly. The standard signal generator calibration method of MOA tester is introduced, based on the description of the characteristics of MOA and testing method. The un- certainty of calibration results of the MOA tester is analyzed and evaluated in detail. The reliability of calibration results and the rationality of uncertainty are verified by using transfer comparison method through the comparison with the calibration results provided by National High Voltage Metrologieal Station. This paper provides a method for the calibration and uncertainty evaluation of the MOA tester, which is helpful to improve the accuracy and consistency of the value transfer of the MOA tester.
