The Multilin HardFiber System is an IEC 61850 Process Bus Solution that allows the mapping of measurements made in the switchyard to protection relays located in the control house using secure communications. The HardFiber System addresses the key technical and logistic challenges affecting the labor required for substation design, construction and maintenance. The HardFiber System is designed to 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, the HardFiber System allows for greater utilization and optimization of resources with the ultimate goal of reducing the Total Life Cost (TLC) for protection & control.

Multilin HardFiber System An Industrial Revolution for Protection & Control The HardFiber 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...

Multilin HardFiber System The Challenges of Copper Wiring With the introduction and progression of microprocessor-based protection and control devices, there has been the continued integration of discrete functions into a single device. This integration has delivered cost savings in terms of materials, but the installation uses the same labor-intensive technology dating back to electromechanical relays. Copper wiring is installed in a substation to integrate the protection and control devices by providing a set of signal paths to move raw information, in the form of analog currents and voltages,...

Multilin HardFiber System Adhering to existing practices: Added benefits: Process Bus is a term used to describe a protection and control system that uses a digital communications architecture to carry information between the switchyard and protection and control devices in the control building. This information consists of sampled values, equipment status and output commands. IEC 61850 is the international standard that defines the specific communication protocol for Process Bus implementations used for protection and control applications. • Providing a complete system with all the necessary...
