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 80% of the total electrical energy. 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 transient 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 electricity enterprises to establishPower quality monitoring仪To achieve real-time monitoring of the power quality of the entire distribution network. Product features:

1. Monitoring of power quality parameters

It can measure the voltage, current, and frequency of three-phase three wire and three-phase four wire (three voltage, four current), and record their changing trends. It 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. It can measure the imbalance of three-phase four wire electrical systems and record its changing trend.

It can measure the 1-25th harmonic and total harmonic distortion of three-phase four wire (three voltage, four current), and record the trend of a certain harmonic. It can also measure voltage fluctuations and flicker.
