Power Quality refers to the reliability and stability of electrical power supplied to equipment and systems. Good power quality ensures consistent voltage, frequency, and waveform, minimizing interruptions, surges, or distortions that can damage sensitive equipment. Poor power quality can lead to equipment failure, reduced efficiency, data loss, and increased maintenance costs. Monitoring and improving power quality is essential for industrial plants, commercial facilities, and critical operations to maintain productivity, reduce downtime, and enhance the overall performance and lifespan of electrical systems.
