Praetorian Fiber Optic Sensing for Power Cable Monitoring

Brand: Hawk Measurement Systems

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.
Features
  • 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
