The P54 MiCOM 5th Generation range of transmission-class protection relays provide high speed current differential unit protection. They are designed for overhead line and cable applications, interfacing readily with the longitudinal (end-end) communications channel between line terminals. The interface options support direct fiber optic or multiplexed digital links.

Multilin UR Family
Proven, State-of-the-Art Protection & Control Systems
The Universal Relay family of protection and control products is built on a common modular platform. All UR products feature high-performance protection, expandable I/O, integrated monitoring and metering, high-speed communications, and extensive programming and configuration capabilities. The UR is the basis of simplified power management for the protection of critical assets.

Key Benefits

  • Modular construction via common hardware, reduced spare parts, and plug-and-play modules for cost savings and simplification.

  • CyberSentry UR provides robust network security aligned to industry standards and services.

  • Application flexibility with multiple I/O options, including high-density I/O, programmable logic, modularity, and specific customization

  • Advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation, complete settings via SCL files, and comprehensive process bus support (IEC 61850-9-2LE, IEC 61869, or IEC 61850-9-2 Hardfiber) ensure interoperability, device management optimization, and reduced cost of ownership.

  • Routable GOOSE (R-GOOSE) enables GOOSE messages to go beyond the substation, which enables wide-area protection and control applications.

  • An integrated large, full-color display provides real-time visualization and control of the protected bay via a bay mimic, as well as annunciator functionality and graphical visualization of phasors.

  • Three Ethernet ports enable purpose-specific LAN support, reducing latency from heavy traffic on critical communications.

Interoperability with Embedded IEC 61850

Process Bus System represents a true breakthrough in the installation and ownership of protection and control systems by reducing the overall labor required for substation design, construction, and testing. This innovative solution addresses the three key issues driving the labor required for protection and control design, construction, and testing:

  • Every substation is unique, making design and drafting a one-off solution for every station.

  • Miles of copper wires need to be pulled, spliced, and terminated.

  • Time-consuming testing and troubleshooting of thousands of connections must be performed by skilled personnel.

The HardFiber System was designed to address these challenges and reduce the overall labor associated with the tasks of designing, documenting, installing, and testing protection and control systems. By specifically targeting copper wiring and all of the labor it requires.UR delivers process bus through the HardFiber System or 61850-9-2LE/61869 process bus module. They allow for greater utilization and optimization of resources with the ultimate goal of reducing the Total Life Cost (TLC) for protection & control.
