Early Fault Detection (EFD) system

24/365 network management

The EFD system is a preventative maintenance technology that remotely detects and locates radio frequency (RF) signals emitted by incipient energy asset faults, i.e. situations likely to develop into permanent faults or wildfire if left unremedied. EFD works independently of the mains-frequency operation of the power system and finds emerging low-current faults just as well as it finds high-current ones. 


The system is a combination of both hardware and software elements. Its architecture comprises of wireless sensors, edge computing and an innovative IoT platform.


EFD's fixed hardware is placed at intervals of multiple kilometres apart and are ‘listening’ for emerging issues.  


EFD utilises GPS satellite network, offering very accurate time-synchronisation for signal detection, location of an emerging fault signal source can be pin-pointed to an extremely accurate location (±30 feet).


The software features of EFD includes continuous data streaming, big data analysis, cloud-based information management, machine learning, real-time data analytics, system alerts and 24/7 device connectivity. Our source data is transferable and we encourage our customers to use it for other purposes. 


Proven performance


The EFD system can reveal many of these conditions before they develop into electrical faults. This can guide preventive maintenance responses including vegetation management, replacement of failing and damaged equipment, and optimisation of pre-emptive asset replacement programs. 


In conditions of high fire or network supply risk, even faster response processes can address rapidly emerging high-risk situations detected by the EFD system.


What can a customer expect? 


To date the EFD system has been proven to successfully detect the following items remotely, proactively, in real-time and down to 30 feet:  

  • Imminent pole fires; 
  • Deteriorated and broken conductors;
  • Cracked and dirty insulators;
  • Touches and close approaches from vegetation on primary and secondary circuits;
  • Mechanical failures of pole top structures;
  • Animal-related activity;
  • Conductor clash or slap;
  • Conductor with bullet damage;
  • Secondary subsidiary issues;
  • Fuse mal-operations;
  • Lightning damaged plant;
  • Deteriorated underground and overhead cables; and
  • Internal equipment insulation breakdown in assets such as pole top transformers.


Award-winning preventative maintenance technology

The best way to learn  about our EFD system is to arrange a formal presentation and demonstration by one of our subject matter experts.
