The Traveling Wave Fault Location System TFS-2100 provides accurate fault location solution for transmission and distribution power lines.
The fault distance Measurement error is less than 500m irrelevant of line length, and free from influences of following factors, which affect fault location accuracy of traditional impedance measurement methods.
Not like the impedance measurement methods which can locate short-circuit faults in normal AC power lines only traveling wave technique can be used to measure distance to fault in all kinds of power lines, including :
& AC transmission lines
& HVDC transmission lines
& Seriously compensated transmission line
& Lines with T branches
& The line containing cable sections and overhead line
& Measuring fault distance of a single phase to ground fault in non-effectively earthed distribution system.
Specially developed software for transmitting and storage for fault data.
