Power quality measurement
Failure of the equipment of the power system will affect the stability of the operation of the system. The heat generated by the fault current is proportional to time. If it lasts for too long, it is easy to damage the power equipment. It is necessary to quickly turn on and off the fault current to reduce the damage to the power equipment.
1. The importance of power quality analysis：
(1) Ensure the normal operation of the equipment：Power quality problems, such as voltage fluctuations, frequency changes and harmonic distortion, can have a serious impact on electrical equipment and may even cause equipment damage. Through power quality analysis, these problems can be discovered in a timely manner and effective measures can be taken to ensure the normal operation of the equipment.
(2) Improve production efficiency：In industrial production, power quality problems can cause unstable operation of production equipment and affect production efficiency. Through power quality analysis, the stability of power supply can be improved, the production process can be ensured smoothly, and production efficiency can be improved.
(3) Save energy：Power quality problems can lead to waste of power and increase energy consumption. Through power quality analysis, these problems can be identified and solved, power utilization efficiency can be improved, and energy can be saved.
(4) Reduce power outages：Power quality problems are one of the important causes of power system failures and power outages. Through power quality analysis, potential problems can be discovered and solved in a timely manner, the occurrence of power outages can be reduced, and the reliability of the power system can be improved.
(5) Protect the environment：Power quality problems can cause a lot of electromagnetic interference in power equipment and cause adverse effects on the environment. Through power quality analysis, electromagnetic interference can be reduced and the environment can be protected.
2. Application areas of power quality analysis：
(1) Industrial field：In industrial production, power quality analysis can help enterprises improve production efficiency, ensure stable equipment operation, and reduce production costs.
(2) Commercial field：In commercial operations, power quality analysis can ensure the normal operation of office equipment and electronic products, improve work efficiency and service quality.
(3) Family field：In household electricity consumption, power quality analysis can protect household appliances, extend their service life, and improve electricity safety.
(4) Public facilities：In public facilities, power quality analysis can ensure the stability and reliability of power supply and ensure the normal operation of public services.
