中文摘要：

对真空吸尘器产品的谐波电流发射测量受到其工作状态的影响进行了分析和讨论。从谐波电流限值要求进行分析，对吸尘器触发角这一工况参量对实际测量结果的影响进行了详细分析，并给出了在实际检测过程中的合理流程。使用三个真空吸尘器样本进行现场试验，对不同谐波电流检测方式所得测量结果进行比较，证明了对触发角所得结论的准确性。

英文摘要：

The harmonic current emission measurement of vacuum cleaners was affected by the operation condition of equipment under test, which was analyzed and discussed in detail in the paper. The requirements of harmonic current were also analyzed. As one of important operation conditions, the phase firing-angle affected the measurement results significantly. A kind of modified testing procedures was provided. The measurement results from three different samples are analyzed, which demonstrates the veracity of the result.
