摘要
结合多年的检测经验,对UL功率因数算法及其影响因素进行了研究和分析,得出影响测量精度的关键因素是采样率。同时,提出了测量系统的采样率必须在10 k Hz以上,才能保证测试数据的准确性、一致性和有效性。
Based on years of testing experience,the UL power factor algorithm and its influencing factors were studied and analyzed. It was concluded that the key factor affecting the measurement accuracy is the sampling rate.The sampling rate of the measurement system must be above 10 k Hz,which can be used to ensure the accuracy of data,data consistency and validity.
