A protective relay is an intelligent device that receives inputs such as current, voltage, resistance, temperature, and even light, compares them with set points, and provides visual feedback, communication, and other outputs in the form of indicator lights and/or alphanumeric displays, controls warnings, alarms, and turns off and on power. They are used for motor protection and ground fault protection in industrial environments. Regulating relays are a special category of protective relays that activate when operating parameters deviate from pre-set limits. Protective relays can be based on electromechanical or solid-state relay technology. In low-power applications, electromechanical design has mostly been replaced by solid-state devices. However, electromechanical relays continue to be used for high-power applications in power transmission and distribution systems. Microprocessor based protective relays can detect small changes in parameters such as voltage, current, resistance, or temperature, which can be used to identify problems in the early stages before they become severe enough to trip traditional protective devices such as circuit breakers or fuses. Protection relays can detect fault causes that cannot be recognized by traditional protection devices, such as overcurrent, overvoltage, or temperature rise
