Power Cable Monitoring System

Forecasting power cable system's reliability in future by means of on-line monitoring and analysis

The power cable monitoring system provided by Sumitomo Electric, such as OPTHERMOTM and AOLCM system, contributes to robust asset management of power cable systems with real time monitoring of the system operation status. These monitoring devices can also be utilized for other applications such as downhole monitoring of oil / gas wells, LNG tanks, Tunnel fire detection. Our solutions include not only real time system monitoring but also prediction and simulation of future load status in order to maximize the use of transmission system.

OPTHERMO

Features

Fiber-Optic distributed temperature sensing system

OPTHERMOTM is a distributed temperature sensing system that uses optical fibers as sensors. Since the optical fiber, embedded inside or attached to the Power Cable, itself is used as the temperature sensor, this system is considered as the best solution for continuous measurement of cable temperatures over a long distance and wide area with significantly high temperature and special resolutions.
