BALMUDA电水壶在那修谐波有功

　　First select the rated voltage of the detected power quality analyzer、Rated current as a fundamental power verification point，Base wave power factor is1；For each harmonic 巴慕达电风扇售后网点 voltage、Harmonic current content and harmonics can refer to the following table1Shown，Harmonic power factor is1.

　　Test the harmonic voltage and harmonic current of the same frequency component simultaneously when the test is verified.，And harmonic power of a single frequency each time，Harmonic voltage Hu base wave voltage;Each channel for multi-channel quotation instruments should be verified，The checkpoint BALMUDA手冲壶售后服务 of the verification point refers to the selection of single-channel power quality analyzer。

　　table1：Harmonic active power verification point recommendation form

　　According to standard requirements，Refer to the following table after the test is completed2Compared，The harmonic active power measurement error in the detected power quality analyzer cannot exceed the specified 巴慕达台灯在那修 value defined in the table.。

　　table2：Harmonic active power allows error limit
