Power quality monitoringIt refers to the real-time monitoring and analysis of various indicators of electrical energy, ensuring the stability, reliability, and compliance with corresponding standard requirements of electrical energy supply. With the continuous development of the power system and the widespread use of electrical equipment, power quality issues have become increasingly prominent, affecting production, operation, and all aspects of people's daily lives. Therefore,Power quality monitoringIt has significant significance and has been widely applied in multiple application fields.

Firstly, power quality monitoring plays an important role in the operation and management of power systems. The power system is a complex energy conversion and transmission system that needs to ensure the stable operation of the power grid. By monitoring power quality, abnormal situations in the power grid can be detected in real time, and measures can be taken in a timely manner to improve the reliability and stability of power grid operation. For example, by monitoring parameters such as voltage, current, and frequency of the power grid, problems such as voltage fluctuations and frequency anomalies can be identified, and adjustments can be made in a timely manner to prevent interruptions and accidents in the operation of the power grid.

Secondly, the application of power quality monitoring in industrial production is also very extensive. Industrial production requires high power quality, and a stable power supply is the foundation for ensuring production and operation. By monitoring power quality, problems in the power supply system can be identified in a timely manner, such as voltage fluctuations, harmonic disturbances, power imbalance, etc. The root cause of the problem can be identified, and corresponding measures can be taken to improve and repair it, ensuring the normal operation of production equipment. In addition, for industries that require strict control over power quality, such as semiconductor manufacturing and precision instrument manufacturing, accurate power quality monitoring is also necessary to ensure the stability of the production process and the consistency of product quality.

Thirdly, power quality monitoring also plays an important role in the inspection and maintenance of power equipment. For the inspection and maintenance of power equipment, it is necessary to conduct comprehensive monitoring and analysis of power quality to evaluate the operating status and health status of the equipment. By monitoring the power quality of equipment, faults and hidden dangers can be identified in a timely manner, the lifespan and performance degradation of equipment can be predicted, corresponding maintenance plans and measures can be formulated, and the reliability and maintenance efficiency of equipment can be improved. For example, in the maintenance of transformers, by monitoring the power quality, the load and temperature rise of the transformer can be determined, and maintenance work such as oil inspection and insulation inspection can be carried out in a timely manner.
