OVERHEAD LINE FAULT LOCATOR

Traveling waves are voltage and current surges propagating along the power line, arising from power system disturbances such as fault, switching operations and lightning. The TFS 2100 traveling wave fault locator, determines distance to fault by measuring the time for a surge to travel from fault position to measurement point. The fault distance measurement error is less than ±150 typical regardless of the line length, and free from the influence of factors which affect fault location accuracy using traditional impedance methods.
