  • PrismaPower™ Grid Monitoring Solution
    PrismaPower keeps your transmission grid up and running, monitoring overhead and underground powerlines to accurately identify physical damage, extreme weather & electrical faults without false alarms....

  • PrismaPower enables transmission system operators to monitor overhead and underground power lines accurately for hundreds and thousands of kilometers in real time without installing any additional sensors on power lines or towers. Instead, it’s an easy deployment, utilizing the existing optical fiber network on top of the transmission grid. PrismaPower Identifies safety events such as physical damage, extreme weather, electrical faults, and physical-cyber attacks.

    With a short ramp-up time and effort, PrismaPower is effective on the installation day. Reflecting a significant cost reduction in grid monitoring, it is a solution that is always there, 24×7, anywhere, anytime, and in any weather.

    PrismaPower Use Cases:

    • Corona, partial discharges, and
    • flashovers
    • Short circuits
    • Wildfires
    • Extreme wind and icing
    • Network failures and inefficiencies
    • Vandalism
    • Lightning strikes
    • Vegetation hits

    Solution architecture:

    PrismaPower turns the existing Optical Ground Wire (OPGW) into a set of highly sensitive distributed sensors extending for hundreds and thousands of kilometers. The solution connects to one single dark fiber at a substation, sensing the grid. PrismaPower’s machine learning algorithms take the detailed data collected on the grid to detect and classify events, pinpointing them down to tower locations in real-time. As a result, alerts have unprecedented accuracy – removing the nuisance of false alarms.​

    Each unit covers 100km of power lines concentrating all the information and alerts into one command and control center. This way, PrismaPower can continue scaling with the grid. Moreover, with the revolutionary Pay-as-You-Grow service model – PrismaPower is your way to take off some of the burdens of responsibility.
