The Power Quality solution includes the analysis, diagnosis, and mitigation of electrical disturbances that affect the performance, service life, and reliability of critical equipment and systems.

The architecture is structured to identify and address phenomena such as voltage variations, harmonics, phase imbalances, fluctuations, transients, and interruptions, ensuring operational stability and reducing recurring failures.

A3A Engenharia de Sistemas develops each solution based on technical measurements, modeling of electrical network behavior, and definition of corrective strategies, ensuring predictable performance and integration with protection and uninterruptible power systems.
