Schneider Micom P441 Full Scheme Distance Protection relays

Schneider MiCOM P441, P442 and P444 are numerical, full-scheme distance relay 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.
Schneider MiCOM P441, P442 and P444 relay 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.
Inter MiCOM, 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 Schneider MiCOM P441, P442 and P444 relay 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.
