Power quality refers to the consistency and reliability of electrical power, encompassing factors like voltage stability, harmonics, surges, and interruptions. Maintaining good power quality is crucial to prevent equipment malfunctions, reduce downtime, enhance energy efficiency, and support the operation of sensitive electronics. Measures such as voltage regulation, harmonic filtering, and monitoring are employed to ensure high power quality, particularly in industrial settings and critical applications. In our digital age, maintaining optimal power quality is essential for the reliability and performance of electrical systems and connected devices.
