电气运维高手使用Fluke319钳表低通滤波器LPF实现变频设备精准测量，文章来源于福禄克公司。随着更为广泛的工业环境，特别是越来越多的变频、整流器、逆变器等设备的使用，实际的波形越来越多样化，甚至引入了越来越多的高频噪声。因此要对这些设备准确测量，真有效值成为其中重要的因素之一。提到噪声或着谐波，不得不说另外一个重要的概念：低通滤波器(LPF)。言下之意，只有低频电流电压才能被测算，高频的部分就会被截至不予计算。可以说，只有具备了低通滤波的真有效值钳表，才是真正有价值的‘真有效值’。福禄克钳表的明星型号F317 /319真有效值交直流钳表，则内置了800-900Hz低通滤波器。这两点的加持使得F317/319可以轻松搞定复杂变频电气设备，同时克服各种恶劣强干扰环境，保证测试数据的精准与稳定性。
Electrical O&M "Old Driver" Uses F319 Clamp Meter to Achieve Accurate Measurement of Inverter Devices, Article from Fluke, Inc. With the use of more and more devices in a wider range of industrial environments, especially frequency converters, rectifiers, inverters, etc., the actual waveforms are becoming more and more diverse, and even introducing more and more high-frequency noise. Therefore to measure these devices accurately, the True RMS becomes one of the important factors. When it comes to noise or harmonics, another important concept has to be mentioned: the low pass filter (LPF). This means that only low-frequency currents and voltages can be measured, while higher frequencies are not counted. It can be said that only a true RMS clamp meter with low-pass filtering is really worth its weight in 'true RMS'.The F317 /319 True RMS AC/DC Clamp Meter, Fluke's star model, has a built-in 800-900Hz low-pass filter. The addition of these two points makes the F317/319 can easily handle complex frequency conversion electrical equipment, while overcoming a variety of harsh and strong interference environment to ensure the accuracy and stability of test data.
