Numeric Protection Relays are advanced microprocessor-based devices designed to protect electrical equipment from abnormal operating conditions. These relays replace conventional electromechanical relays by offering multiple protection functions in a single unit. They continuously monitor system parameters such as current, voltage, frequency, and power.The relay provides precise fault detection, fast tripping, and accurate isolation of faulty sections, improving system reliability and safety. Integrated event logs, fault records, and self-diagnostics support easy troubleshooting and maintenance. Suitable for industrial plants, substations, power distribution panels, and utility networks.
