The challenge

What operators are up against

Operators responsible for overhead transmission lines, optical ground wire, conductors, towers, insulators, vegetation, icing, wind, electrical faults, line temperature, sag, and grid operators cannot continuously inspect every operating condition or developing fault. Periodic checks leave gaps between readings, while isolated local indicators provide limited history and context. A late response can cause downtime, safety exposure, equipment damage, or incomplete compliance evidence. Teams need timely measurements, clear exceptions, and a defined operating response.

The solution

How Fiber-Optic Power Transmission Grid Condition Monitoring addresses it

Fiber-Optic Power Transmission Grid Condition Monitoring combines connected field data with application software. Hyper-Scan distributed fiber sensing captures vibration, acoustic, thermal and strain signatures along long power corridors using existing optical fiber. PrismaPower locates and classifies weather, vegetation, mechanical, electrical and asset events while supporting dynamic line condition and capacity insight. Grid teams investigate threats, dispatch inspection or repair, clear vegetation, respond to faults, plan maintenance, and operate lines.

How it works

Teams configure the monitored assets, users, and operating rules. Hyper-Scan distributed fiber sensing captures vibration, acoustic, thermal and strain signatures along long power corridors using existing optical fiber. The solution turns existing optical fiber into a distributed sensor and carries analyzed event and location records through the deployed system path. PrismaPower locates and classifies weather, vegetation, mechanical, electrical and asset events while supporting dynamic line condition and capacity insight. Grid teams investigate threats, dispatch inspection or repair, clear vegetation, respond to faults, plan maintenance, and operate lines.
