Distributed Optical Fiber Temperature Online Monitoring Solution
Overview
Optical fiber temperature measurement system is the world’s most advanced and effective continuous distributed temperature monitoring system. It has been widely used in electricity system for real-time online temperature monitoring of power cable line. Its continuous, real-time and distributed temperature monitoring can accurately capture abnormal hot spot, let the cable fire be nipped in bud and ensure secure and healthy operation of the whole system.
Scope
Cable tunnel, cable interlayer, cable shafts, cable trench, high voltage cables and etc.
