        Power quality monitoring is an important part of finding power quality problems, which can be used to determine the cause of equipment misoperation. Power quality monitoring is a direct means to obtain power related data, accurate information can provide useful clues for the solution, power quality online monitoring device can quickly and systematically display these useful information.

         Power quality monitoring is the premise of analyzing and solving power quality problems, and it is also the basis of whether power companies and power users are responsible for power quality problems in accordance with the requirements of the agreement. Power quality online monitoring device can help users monitor the power grid environment for a long time, understand the power quality status in real time, find power grid abnormalities, locate problems as soon as possible, and provide basis for solving problems.

        All analog channels of power quality online monitoring system adopt 16ad synchronous sampling, and the sampling point of weekly wave is 1024, that is, the sampling speed of 51.2k. The accuracy of current and voltage measurement can reach 0.2 level. It has the advantages of high conversion accuracy, fast conversion speed and synchronous sampling. At the same time, in order to prevent the measurement error caused by the frequency deviation from the rated value, the device adopts hardware phase-locked loop technology, automatic frequency tracking and timely adjustment of sampling interval to prevent frequency "loss".
