Single-end fault locator (FL)
The function of the single-end fault locator (FL) is to determine the location of faults that occur
on a transmission line with a high degree of reliability. Determination of the location of faults
provides a useful contribution to the recovery of circuits in the event of power system failures.
Fault location is provided by the FL function; computation is based on impedance-based
algorithms using information at the local end of the line only.
