泄漏电流测量方法的不确定度评估

Uncertainty Evaluation of Leakage Current Measurement Methods

以双重绝缘角向磨光机为例,从随机因素、固有误差、灵敏度误差、电压波动、金属箔面积以及紧贴放置程度、电源频率变化、试验室温湿度变化、器具加载电流波动等多方面分析泄漏电流检测过程中可能出现的测量误差,从而对测量方法的不确定度进行评估。

With double insulation angle grinder as an example, from random factors, the inherent error, sensitivity error, voltage fluctuations, the area of the metal foil is placed against the degree, the power frequency, the test temperature and humidity changes, the appliance load current fluctuations, and many other analytical measuring the leakage current detection error may occur during the test, to evaluate the uncertainty of measurement methods.
