What is one of the primary functions of a power quality analyzer?

A power quality analyzer serves several important functions, with one of its primary roles being to assess the quality of the electrical power supply. This involves monitoring various parameters that can affect the performance and stability of electrical systems, such as voltage sags, swells, harmonic distortion, frequency variations, and transient voltages. By evaluating these factors, the analyzer helps to identify issues that may lead to equipment malfunctions, operational inefficiencies, or potential damage.

This capability is essential for maintaining a reliable power system, ensuring that all connected devices receive a consistent and high-quality electrical supply. Such assessments can also aid in diagnosing existing problems and preventing future failures, thereby contributing to overall system reliability and performance.
