The "portable recorder" is mainly used in electric power companies to find fault points and analyze test data when they are doing various tests, find data abnormalities, and find out the cause of the fault. The "portable recorder" has three functions: recorder function, power quality test function, generator excitation test function. Therefore, the purchase of products should focus on these three functions. Let's take the "WFLC-VI portable wave recorder" of Guoyi Technology as an example. First of all, the wave recording function; it collects as many channels as possible, up to 12 low voltage, current analog data acquisition, 5 passive node switching measurement channels, and can edit the collected curve, including its own logo, color Transformation, scaling and positioning operations. Second, the power quality function; it performs harmonic analysis on the collected signals, and the highest harmonic is 1024 times. The last point is the excitation test test function. It uses accurate tests for generator short circuit test, no-load, disturbance, de-excitation time, frequency voltage, load rejection, and self-aligning synchronization test, and can draw curves. In short, the "portable fault recorder" is a very powerful product. There are many items to be tested. If you choose and use this type of product, it is best to consult the manufacturer.
