The analysis of power quality mainly focuses on four aspects.
To achieve a true analysis of power quality, correct analysis comes from four main aspects: 1. Continuous recording The advantages of continuous recording for improving practicality and solving erroneous trigger value settings are obvious. Many case studies illustrate that correct analysis cannot be conducted without the aid of continuous recording.

What is the purpose of supervising and managing power quality?
The quality of electric power is directly related to the supply safety and quality of the power system. Exceeding the standards of electric power quality, regardless of which parameter is exceeded, may cause abnormal operation of electrical equipment. In severe cases, it may even damage the equipment and bring many hazards.
