Micom P22x Motor Protection Relays

Product Description

The MiCOM P22x protection relay range is designed for motor protection applications. A complete set of protection functions is performed on the measurement of current, voltage and temperature. In addition to these basic functions, the relay carries out a large number of other functions that enable it to protect and run the motor more effectively. The reliability of the system is further enhanced via checks on bus voltage prior to start-up during reacceleration, supervision of trip-circuit wiring continuity and protection against circuit-breaker failure. The MiCOM P22x protection relay range is particularly adapted to oil refinery, chemical plant, metallurgy, glass and cement manufacturing, paper mills, electrical and mechanical engineering, food production, mining etc. It is also suitable for water treatment and in pumping stations as well as in steam power plants. On top of that high inertia loads and anti-backspin protection ensures that the rotor stops before the motor can be re-started. For motors whose current supply contains a considerable degree of distortion, the relay provides a true RMS base thermal image allowing efficient protection against overload phenomena due to the presence of harmonic components. The addition of power measurement* and energy metering*, and the presence of analogue outputs (current loop) make the MiCOM P22x protection relay range a highly competitive and effective equipment in terms of protection. With latest upgrade P225 now can provide optional Ethernet communication with 2 RJ45 interfaces.
