影响电压暂降能力验证结果的原因分析

Cause Analysis of Affecting Results of Voltage Dips Proficiency Test

对电压暂降能力验证结果不满意的案例进行分析,通过设计几组实验,分析了电压暂降不良的原因。确定了影响电压暂降能力验证结果的两个重要因素(电源电压波形畸变和变压器变比误差),为实验室的质量控制提供指导。

According to the analysis of unsatisfactory results of voltage dips interruptions proficiency test. Two significant factors (distortion of supply voltage waveform and transformer ratio error) to impact the voltage dips performance were identified per designed experiments to analyze bad voltage dips performances, it provides better guidance for the quality control of laboratory.
