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 needs 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. Learn more
