Schneider Micom P442

Schneider Micom P442 Relay, MiCOM P441, and P442 are numerical, full-scheme distance relays that provide protection control and monitoring of transmission lines.
These numerical full-scheme relays provide flexible and reliable protection control and monitoring of transmission lines. They can be applied to high and extra-high voltage systems and operate extremely quickly and securely.
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 fast operating times as low as 0..85 cycles. Offering a wide choice of channel-aided schemes, this MiCOM family provides Power swing detection and Out-of-Step protection. Users may also choose from multiple communication protocols and interfaces options, including IEC61850.
