Transmission and distribution lines
 |
Providing electricity without interruption to a growing market is a challenge for power engineers. |
| The real challenge is to meet the growing energy demand whilst maximizing cable capacity, minimising costs, environmental effects, and embracing the requirements of this dynamic industry where the life span of an asset may be in excess of 40 years. |
The benefits of energy cables monitoring is the ability to postpone investment in the circuit, since if the temperature of the cable is known in relation to load, maintenance time or replacement interval can be scheduled according to actual cable behaviour, rather than the predicted replacement date, which is usually sooner.
Power transmission lines - monitoring approach
Omnisens systems continuously monitor the entire power cable. Very small variations in temperature are detected with a high temperature resolution (0.1°C) over up to 50km with meters spatial resolution. The detection of temperature variations allows operators to track anomalies and anticipate failures at a very early stage and avoid huge operation costs associated to a power outage.
