PAD1000 Power Quality Analyzer

Power quality refers to the quality of AC electricity supplied to users through the public power grid, and in layman's terms, it refers to the quality of electricity in the power grid lines. The power quality issues are mainly caused by the terminal load side. For example, impulsive reactive loads can cause severe voltage fluctuations in the power grid, reducing the quality of power supply.

With the development of power electronics technology, it has brought positive aspects of energy conservation and energy conversion to modern industry. At the same time, the widespread application of power electronic devices in various industries has also caused new and more serious damage to power quality, and has become the main source of harmonic pollution in the power grid.

The use of rectifiers, variable frequency speed regulation devices, electric arc furnaces, electrified railways, and various power electronic equipment in the distribution network of various user terminals in the power grid system is constantly increasing. Causing impact on the electricity network or electricity pollution. Causing voltage instability, overvoltage, harmonic generation, etc. Harmonics reduce the efficiency of the production, transmission, and utilization of electrical energy, causing electrical equipment to overheat, generate vibration and noise, and lead to insulation aging, shortened lifespan, and even failure or burnout. Harmonics can also cause local parallel resonance or series resonance in the power system, amplifying the harmonic content and causing equipment such as capacitors to burn out.

The nonlinear, impulsive, and unbalanced electrical characteristics of these loads cause serious pollution to the quality of power supply. Therefore, eliminating high-order harmonic problems in the power supply and distribution system has a very positive significance for improving power quality and ensuring the safe, stable, and economical operation of the power system.

On the other hand, modern industrial, commercial, and residential users' electrical equipment is more sensitive to power quality and has higher requirements for power supply quality. At present, harmonics, electromagnetic interference, and power factor reduction have been listed as the three major public hazards in the power system.

When the power quality of the power grid is disrupted or polluted, and cannot meet the relevant national standards, targeted improvement of the power quality of the power grid is necessary. To understand the actual situation of power quality in the power grid, it is necessary to have corresponding equipment for testing and analysis. Based on the actual situation in China, our company has timely developed professional power quality analysis instruments that are suitable for the national conditions. Below is a detailed explanation of the specific performance, parameters, and usage methods of the power quality analyzer.
