       As a professional measurement tool, power quality on-line monitoring device can record and analyze power quality problems in power grid. It can capture harmonic, voltage fluctuation, flicker, power and three-phase imbalance and other common power quality problems on the fault site. It can reflect the AC power quality of users in the public power grid, and all kinds of electrical equipment in different operating conditions have different impact on the public power The influence of network power quality.
       All kinds of power events in the power grid often indicate some abnormal power grid quality. It will be of great help to find out these anomalies in time and take corresponding measures to ensure the power quality and reduce the economic losses and accidents caused by the anomalies. If we can't find the abnormal power events in the power grid in time and deal with them effectively, it will cause serious safety accidents.

      There are a large number of nonlinear, impulsive and fluctuating loads in power system, such as high-power frequency conversion equipment and driving device, electrified railway, rectification equipment of electric chemical industry, induction heating furnace, electric arc furnace, etc. these loads cause waveform distortion (harmonic), voltage fluctuation, flicker, three-phase imbalance and asymmetry of power grid, and reduce the power quality of power grid Low.

Precision electronic instruments based on computers and microprocessors are widely used in national economic enterprises. They are more and more sensitive to the quality of power supply, and put forward higher requirements for power quality. Therefore, the problem of power quality and its solutions have gradually become the research of thermoelectricity. To improve the power quality of power grid, first of all, it is necessary to make accurate detection and analysis of power quality, measure the power quality level of power grid, and analyze and judge the causes of various power quality problems, so as to provide basis for improving power quality.

      The online power quality monitoring device is connected with the background management system through Ethernet. It only needs one installation and deployment to realize long-term and stable power grid quality monitoring. It can monitor and analyze the power grid data more safely and efficiently. It can realize real-time data automatic collection, real-time detection and notification of abnormal events, so as to avoid accidents caused by power quality problems and reduce economy Loss.
