Schneider MiCOM P145 feeder management relays

Schneider MiCOM P145 is a relay protection device for feeder management from Schneider Electric, which has an important role in power systems, and is described below:

Functional features:

Comprehensive protection functions: With overcurrent protection, ground fault protection and other functions, it can provide complete power system protection for feeders, and can be applied to MV/HV, effectively grounded, impedance grounded, Peterson coil grounded and neutral point insulated systems, providing reliable primary or backup protection for all kinds of power grid applications.

Advanced Communication Capabilities: Supports a wide range of digital control system protocols for easy integration into Distributed Control Systems (DCS), Supervisory Control and Data Acquisition (SCADA) systems, and engineering workstations, as well as IEC 61850 communication protocols for efficient data interaction and remote control.

Flexible Configuration and Control: With function keys for parameter setting and system control of the overall program control functions, it is convenient for users to flexibly configure and operate the protection device according to actual needs.

Application Scenario:

Power system feeder protection: applicable to the protection, control and monitoring of overhead lines and underground cables, covering all distribution and transmission voltage levels, capable of providing comprehensive protection and monitoring for complex power systems and their components, helping power operation and maintenance personnel to effectively maintain the stable operation of power systems.

Industrial and commercial fields: In the power supply system of industrial plants, commercial buildings and other places, it can protect and manage feeders to ensure reliable power supply and reduce production interruptions and equipment damages caused by power failures.

Product Advantage:

User-friendly and flexible: with a user-friendly interface, the P14x relay series is highly flexible and can be applied to any network, providing all the necessary information to effectively maintain complex power systems.

Adaptability to harsh environments: With excellent immunity to interference and adaptability to harsh environments, its new advanced optical input meets the most stringent surge tolerance specifications and ESI 48-4 EB2 standards, eliminating stray wiring pickups without the need for intermediate relays, external resistors or delays, and able to withstand battery/wiring failures, switching noise, and inductance of long paralleling circuits without malfunctioning, extending the product's Extended Product Life.
