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.
