Power quality monitoringdeviceFeatures:

The power grid is composed of five links: "generation, transmission, transformation, distribution, and utilization". As the "distribution and utilization" link on the user side, it consumes a significant amount of total electrical energy80%. With the development of social economy, impulsive, nonlinear, and unbalanced loads such as electrified railways, arc furnaces, and frequency converters are increasingly being used in power applications. Power quality issues such as harmonics, negative sequence, flicker, and voltage transients directly affect the power supply of the power system. Electric energy is a commodity, and its quality issues are a common concern for both suppliers and customers. It is necessary for power consumption enterprises to establish a power quality monitoring system to achieve real-time monitoring of the power quality of the entire distribution network.

1Monitoring of power quality parameters:Can measure three-phase three wire and three-phase four wire(Three voltage, four current)Measure the voltage, current, and frequency, and record their changing trends;Can measure the three-phase active power, apparent power, reactive power, power factor, etc. of a three-phase four wire electrical system, and record the trend of changes in three-phase active power;Capable of measuring the imbalance of three-phase four wire electrical systems and recording their changing trends;Measurable three-phase four wire(Three voltage, four current)的1-25Subharmonic and its total harmonic distortion. And record the trend of changes in one of the harmonics;Can measure voltage fluctuations and flicker.
