A Power Monitoring Relay is an electrical device used to monitor and protect electrical systems from abnormal conditions. These relays track critical electrical parameters such as voltage, current, frequency, power, and power factor. When any of these parameters deviate from predefined thresholds, the relay can trigger an alarm, shut down the system, or take corrective actions to prevent damage. Power Monitoring Relays are commonly used in industrial automation, power distribution systems, and facilities management to ensure the safety and efficiency of electrical equipment.
