CableGuardian encompasses proven technology with extensive industrial heritage in challenging environments to provide a distributed and intelligent cable infrastructure health monitoring system for various electrical industries.

Problem

With the increasing age of many cables, cable failures are becoming more of an issue. Cables can fail due to various reasons and these are not always detectable using one method or piece of equipment. Repairs and maintenance require systems to be powered down and the fault located which takes time and resources. 

Solution

CableGuardian is a complete measurement and analytics package which provides live insulation and conductor monitoring and alarms when faults appear. The raw data received from a network of cable guardian nodes is stored and analysed centrally. During an event the operator will receive an alert with useful information regarding the fault type and location. 

CableGuardian locates the position of insulation failure and further locates with 98% accuracy the precise location of any short, open, or transient failure.

Applications

  • Railway signalling power distribution systems
  • Mission critical IT (unearthed) electrical distribution systems

Key Benefits

  • Helps to avoid injury and reduce downtime through early fault detection and location
  • Analytics facilitate proactive, rather than reactive, maintenance
  • Enables faster and more accurate repair, minimising service outage
  • Permits a move from a frequency based inspection regime to one driven by actual asset condition and performance
  • Enables compliance with the requirements of Network Rail Standard NR/L2/SIGELP/27725

Key facts

  • Locates the position of insulation failure and further locates with 98% accuracy the precise location of any short, open, or transient failure.
  • Measures insulation resistance, capacitance, shorts, opens and intermittent faults as well as a range of electrical parameters (voltage, current, frequency, power, Polarisation Index, Dielectric Absorption Ratio).
  • Distributed and intelligent infrastructure for cable health monitoring
  • Enables compliance with the requirements of Network Rail Standard NR/L2/SIGELP/27725
  • Integrity alarms and fault information direct to asset stakeholders
