Answer: A digital substation is a modern substation that replaces traditional copper wiring with fiber optic communication. This allows for seamless, high-speed data exchange between all of the substation's components. Key features include substation automation, which enables remote monitoring and control, and the use of Intelligent Electronic Devices (IEDs) that collect and analyze data. The industry standard for this communication is IEC 61850. A retrofit to a digital substation requires specialized tools for the installation of fiber optic cables and advanced IEDs. While we specialize in power line equipment, we are a key provider of the underground cable laying equipment and tools required for laying the fiber optic and control cables that make these digital substations possible.
