Praetorian Fiber Optic Sensing for Power Cable Monitoring

Praetorian Fiber Optic Sensing for Power Cable Monitoring

The Praetorian Fiber Optic Sensing System can monitor buried and unburied data cables, wires and power transmission lines. Monitoring for wear, damage or corrosion of the cable is extremely difficult and often power failure or data outage is the first sign of a problem. These cables are typically installed in areas that have multiple uses by various stake holders and in the event of a failure can be logistically difficult and expensive to access for repair. The Praetorian Fiber Optic Sensing System can be installed either near the power cables or embedded within the power cable itself. It can monitor disturbances, identify manual and machine excavation, vehicle movement, ground condition assessment and detects hotspots. HAWK’s Fiber Optic Sensing System requires no additional field infrastructure such as power or communication and does not require maintenance or calibration after commissioning.

Industries

  • Mining and Minerals
  • Utility Tunnels
  • Transformers
  • HVAC / HVDC
  • Underground and Above ground Power Cables

Product: FOS-3

Principle of Operation

Using a combination of Rayleigh backscatter, Brillouin backscatter and time of flight, Praetorian determines the presence, location, intensity and frequency of vibrations and temperature changes along an optical fiber in real time. These fibers can be integral to or laid with high voltage power transmission cables and operate as a comprehensive Power Cable Monitoring System (PCMS).

By monitoring both the temperature and vibration from the same system it is possible to detect and locate a wide range of faults detrimental to cable health including predictive detection capable of alerting operators of threats to a cable prior to failure.

  • Detection of hot spots
  • Conductor break detection
  • Underground and Above ground Cable Monitoring
  • Ground condition monitoring
  • Detect issues as a distributed sensor rather than a point sensor
  • Requires no additional field infrastructure such as power or communications
  • 24/7 real-time monitoring
  • Low cost per foot
  • Preventative rather than reactive
  • Autonomous detection with low false alarm rate
  • Perimeter/Border
