Power quality refers to the quality of AC power provided to users through the public grid. Generally speaking, it refers to the power quality of the grid lines. Power quality problems are mainly caused by the terminal load side. For example, the impact of reactive load will make the grid voltage fluctuate violently and reduce the quality of power supply.

With the development of power electronic technology, it not only brings positive aspects of energy saving and energy conversion to modern industry, but also brings new and more serious problems to power quality due to the wide application of power electronic devices in all walks of life. The damage has become the main source of harmonic pollution of the power grid. The number of rectifiers, frequency converters, electric arc furnaces, electrified railways and various electrical and electronic equipment in the distribution network for individual consumers in the grid system is increasing. affect or pollute the power grid. Cause voltage instability, overvoltage, harmonic generation, etc. Harmonics reduce the efficiency of power production, transmission and utilization, cause electrical equipment to overheat, generate vibration and noise, age insulation, shorten service life, and even fail or burn out. Harmonics may also cause local parallel resonance or series resonance of the power system, which amplifies the harmonic content and causes equipment such as capacitors to burn out.

The nonlinearity, shock and unbalanced power consumption characteristics of these loads cause serious pollution to the power supply quality. Therefore, the elimination of high-order harmonics in the power supply and distribution system has a very positive significance for improving the power quality and ensuring the safe, stable and economical operation of the power system. On the other hand, the electrical equipments of modern industrial, commercial and residential users are more sensitive to power quality and put forward higher requirements for power supply quality. At present, harmonics, electromagnetic interference and power factor reduction have been listed as the three major public hazards of the power system.

When the power quality of the power grid is disturbed or polluted and fails to meet the relevant national development standards, it is necessary to improve the power quality management of power grid technology in a targeted manner. In order to understand the actual working conditions of the power quality of the power grid, it is necessary to have corresponding equipment to analyze the control and test data. According to the actual living conditions in my country, our company can timely develop and develop professional power quality problem analysis instruments suitable for our own national conditions. The following is a detailed description of the specific performance, parameters, and use of this method of the power quality analyzer.

Power quality analyzer is a professional instrument used by electric power workers to analyze and test power quality in actual work. It is very popular among electric power workers, so everyone needs to master it.
