Fiber Optic Sensing Solutions

Distributed Acoustic Sensing and Distributed Temperature Sensing are fiber optic sensing solutions which measure temperature along the fiber either utilizing a technique called Coherent Optical Time Domain Reflectometry (COTDR) or Optical Time Domain Reflectometry (OTDR), turning the entire length of a fiber optic cable into a sensor.

The Applications

  • Power cable monitoring including HVAC and HVDC underground transmission power cables, overhead power lines and subsea cables
  • Perimeter Intrusion Detection System (PIDS) including both substation and generating station perimeter protection

Economic advantages of Distributed Acoustic Sensing and Distributed Temperature Sensing

The economics of a solution always comes into play when considering procuring or designing a Distributed Acoustic sensing (DAS), Distributed Temperature Sensing (DTS) and/or Real Time Thermal Rating (RTTR) system as part of a power cable monitoring system. However, it’s often hard to collate information or quantify due the complexities of the systems.

Bandweaver’s article ‘What are the economic benefits of Distributed Acoustic Sensing (DAS), Distributed Temperature Sensing (DTS) and Real Time Thermal Rating (RTTR) systems for transmission and distribution cables?’ discusses this topic and uses a few key data points in order to quantify certain elements of this argument.

The article considers the potential benefits such as improved situational awareness of power cable monitoring, improved security to reduce malicious or accidental Third Party Intrusion (TPI).

Examples of economic gains in utilising DAS, DTS and RTTR systems

Example 1:          How distributed acoustic sensing can help prevent cable damage

Example 2:          Using distributed temperature sensing and real time thermal rating systems to uprate cable

Example 3:          How distributed temperature sensing can provide payback by reducing the downtimes by preventative maintenance of power cables.
