Schneider MiCOM P144 feeder management relays

The Schneider MiCOM P144 is part of Schneider Electric's Easergy MiCOM P14x series of relay protection devices, which are especially suited for complex systems. The following is a detailed description of the P144:

Functional features: Similar to other products in the same series, the P144 integrates advanced communication protocols and supports a wide range of digital control system protocols, which can be easily integrated into DCS, SCADA and engineering workstations, and it also supports the IEC 61850 communication protocol, which enables efficient data interaction and remote control. Meanwhile, it is equipped with complete protection functions, such as overcurrent protection, ground fault protection, etc. It can be applied to MV/HV, effective grounding, impedance grounding, Peterson coil grounding and neutral point insulation systems, providing reliable primary or backup protection for all kinds of power grid applications. In addition, it has function keys for parameter setting and system control of the overall program control functions, allowing users to flexibly configure and operate the protection device according to actual needs.

Application Scenario: It is suitable for the protection, control and monitoring of overhead lines and underground cables, covering all distribution and transmission voltage levels, and can be applied to the protection of power system feeders, providing comprehensive protection and monitoring for complex power systems and their components. It is also suitable for use in power supply systems in industrial plants, commercial buildings and other locations to protect and manage feeders, ensure reliable power supply, and minimize production interruptions and equipment damage caused by power failures.

Advantages: The P14x series has a user-friendly interface, is highly flexible, can be applied to any network, and provides all the necessary information for the effective maintenance of complex power systems, which the P144 naturally possesses. The P144 also excels in its immunity to interference and harsh environments, withstanding battery/wiring failures, switching noise, and long parallel circuits without malfunctioning, extending the life of the product.
