Proven algorithm basis for customized protection control

For use in high and extra-high voltage systems, this MiCOM relay family can be applied to a wide range of overhead lines and underground cables. Their functioning is based on a patented, proven algorithm with more than two decades of established field experience.

MiCOM P441, P442 and P444 offer unparalleled speed, security and selectivity all in one. Designed to protect and control any kind of power system fault, their wide range of communication options help in easily connecting them to any type of Digital Control System or SCADA.

InterMiCOM, an optional protection communication interface and a powerful programmable graphic scheme logic, enable users to develop customized protection schemes and solutions.

Fast, safe operations

Based on dual algorithms and polygonal characteristics, the MiCOM P441, P442 and P444 deliver the fastest operating time of 0.85 cycles per minute? Offering a wide choice of channel-aided schemes, this MiCOM family provides Powerswing detection and Out-of-Step protection. Users may also choose from multiple communication protocols and interfaces options, including IEC61850.
