What is the primary function of a power quality meter?

The primary function of a power quality meter is to measure various aspects of power quality, including voltage stability, frequency, harmonics, and other parameters that influence the quality of electrical power being supplied. This information is crucial for identifying problems in the electrical system, such as disturbances, imbalances, or inefficiencies that can affect the performance of equipment and the reliability of electrical service.

Power quality meters provide valuable data that can help operators and engineers analyze the electric supply's condition, facilitating the resolution of issues that could lead to downtime or equipment damage. By tracking specific metrics, such as voltage dips or swells and total harmonic distortion, these devices are integral to ensuring that power is supplied consistently and reliably, thus maintaining the operational integrity of the electrical system.
