Skip to Main Content Faults that occur on transmission lines are
relatively more common in countries that have extreme weather.
Most faults in such countries are caused by lightning storms.
For long distance transmission lines, it takes a long time to
find the faulted point. This not only prolongs the time of
removing and recovering the fault, but also increases economical
damages. If fault can be precisely located, maintenance crew can
reach the faulted point quickly, and remove the fault in time.
So the precise locating of the faulted point on a transmission
line is very important to remove fault, improvement of system
reliability, and decrease of economic damages as an inherent
consequence of a long term outages. Hence, the fault location
methods become of much importance for utilities and researches.
In this paper, three of single-terminal impedance-based fault
location techniques will be investigated to show the reliability
and deficiency of each technique. TENCON 2009 - 2009 IEEE Region
