When operators leverage digital technology and power systems in real time, it leads to significant improvements in grid reliability, increased site and worker safety, and reduced power interruptions. Enter, the digital revolution. Digital substations reduce the electrical connection between high-voltage equipment, let the grid run more efficiently, and create a safer work site. This is done by replacement of copper signal wires with fiber-optic connectivity. Additionally, the industrial internet of things (IIoT) is able to offer data on demand to optimize overall substation performance — often letting operators work from the comfort and safety of an offsite office.
