What does a power quality meter do?

A power quality meter is designed specifically to monitor and record the quality of electrical power in a system. It provides detailed insights into various parameters that affect power quality, such as voltage levels, current harmonics, power factor, frequency variations, and transients. By analyzing these parameters, it assists in identifying issues like voltage sags, swells, interruptions, and harmonics that can negatively impact equipment performance and longevity.

The focus of a power quality meter is on the analysis and recording of data rather than the direct management or correction of power issues or energy consumption. It serves as a diagnostic tool, enabling electrical engineers and technicians to understand power quality problems and work towards solutions if performance issues arise in the electrical system. This functionality makes it essential for ensuring reliable operation within industrial, commercial, and residential electrical systems.
