PQ (Power Quality) indices

Power Quality (PQ) indices are measurements that evaluate how well electrical power meets the needs of devices and systems. They assess aspects like voltage stability, current consistency, and the presence of disturbances such as surges or noise. Good PQ means reliable, stable electricity that prevents equipment damage and operational issues. Key PQ indices include Voltage Unbalance, Total Harmonic Distortion (THD), and Power Factor. Monitoring these helps identify issues early, ensuring efficient and safe operation of electrical equipment, ultimately supporting continuous and safe power supply in homes, industries, and businesses.
