INTRODUCTION TO MiCOM P220 6.1 MiCOM series relay The range of MiCOM protection relays follows on from the success of the MIDOS, K and MODN ranges by incorporating the last changes in digital technology. The MiCOM P220 is fully compatible and use the same modular box concept. MiCOM P220 provides more protection elements for the most demanding applications. This relay has a large number of control functions and collecting data. This can form part of a fully integrated system covering protection, control, measurements data acquisition and recording of faults, events, and disturbances. The relay is equipped on the front panel with a liquid crystal display (LCD) with 2x16 back-lit alphanumerical characters, a tactile 7 push keypad (to gain access to all the parameters, alarms and measurements) and 8 LEDs simply displaying the state of the relay. In addition, the use of the RS485 communication port makes it possible to read, reinitialise and change the settings of the relay, if required, from a local or remote PC computer equipped with appropriate software. Its flexibility of use, reduced maintenance requirements and ease of integration allow the MiCOM P220 to provide an evolving solution for the problems of the protection of motors.
