FMC Tech has developed a new system for on line measurement of conductor temperature and load, using a modified conductor mounted Fault Passage Indicator (FPI) together with a software system running a thermal model of the overhead line asset. As a result this system enables both dynamic line rating and the location of faults in a single device.
The technological areas are two fold, firstly the conductor mounted FPI:

  • Detects the passage of fault current on distribution networks, recording accurate current waveform data
  • The dynamic rating monitoring solution can be applied, in the management of heavily loaded circuits

  • Delivering potential connection solutions for Distributed Generation (DG), particularly wind where increased wind speed results in higher export, but also greater cooling of the overhead line and therefore providing an increased conductor rating.
