Founded in 2019 by Golam Sadeghnia, Oktogrid is built to deliver key insights on an often-overlooked asset: the power transformer. The innovation is recording acoustic signatures of power transformers, and the solution is delivering power transformer intelligence.

Synthetic images to improve anomaly detection in high-voltage infrastructures

The limited availability of real images of rare anomalies represents one of the main challenges in developing artificial intelligence models for the inspection of electrical infrastructures.

Advanced simulation to reinforce the resilience of anti-cascade towers

When designing the transmission grid, reinforcing the resilience of the grid's infrastructure against extreme weather events or exceptional situations that can cause cascading tower collapses is a fundamental criterion to ensure asset integrity. Overhead lines themselves are structured by incorporating reinforced anchor towers distributed along the route, which also play a key role as anti-cascade towers.
