The Internal Fault Detector (IFD) is a sensor that detects and indicates internal arcing faults in pole mounted and pad mounted distribution transformers . The sensor releases a highly visible orange signal that informs line workers the transformer has an internal fault and needs to be replaced.
The IFD saves valuable downtime whilst improving worker safety. The IFD mechanical sensor provides set-it-and-forget-it operation and a typical 12:1 return on investment over the life of the transformer. If time and safety is your concern, IFD represents the best investment for your network.
