LOCATION OF FAULT
Save time and resources for the electric utility industry.
Determine “distance to fault” from a transmission line end.
Aid in fast restoration of power.
Communication systems can retrieve fault location information.
WHAT IS TRAVELING WAVE FAULT LOCATION?
Faults on the power transmission system cause transients that propagate
along the transmission line as waves.
These waves have a propagation velocity & characteristic impedance , travel from fault location towards line ends
The location of faults is accomplished by precisely time-tagging wave fronts as they cross a known point typically in substations at line ends.
Fault location can then be obtained by multiplying the wave velocity by the time difference in line ends.
