A shortcut to making the grid safer and more reliable: Beams of light

AI generated summary

Prisma Photonics is revolutionizing the monitoring of high-voltage transmission lines by utilizing existing fiber-optic cables to detect disruptions over vast distances. Traditional methods of installing sensors along power lines are costly and time-consuming, but Prisma's technology allows utilities to leverage the optical ground wires already in place. This innovative approach enables the identification of various issues, such as ice buildup and nearby wildfires, by treating the fiber-optic cables as an array of microphones that capture minute changes in the environment.

The company aims to provide a more efficient and cost-effective solution for utilities facing increasing challenges due to climate change and grid reliability. By integrating its optical interrogator devices into substations, Prisma can analyze data from the fiber-optic cables to detect shifts in temperature, pressure, and strain. This capability not only helps in identifying faults more quickly but also allows for dynamic line rating, which can enhance the capacity of existing grids without significant upgrades. As Prisma continues to gather real-world data and validate its technology, it positions itself as a versatile platform for improving the safety and reliability of electrical transmission systems.
