Power Quality refers to the characteristics of electrical power that affect the performance of electrical devices. It includes factors such as voltage stability, frequency consistency, and the presence of disturbances like harmonics or transients. Good power quality ensures that electrical equipment operates efficiently and reliably. Poor power quality can lead to equipment malfunctions, increased energy costs, and reduced lifespan of devices. Common issues include voltage sags, spikes, and flickers, which can disrupt operations in industries and homes alike. Monitoring and improving Power Quality is essential for maintaining the health of electrical systems and ensuring optimal performance.
