Abstract
The locating of a fault on a de-energized power line section is carried out by measuring a reflection signal characterizing the fault and deriving from a voltage signal applied on the section. An application of the voltage signal and corresponding measurements of reflection signals are simulated with a model of the section for a fault located at different locations along the section. The simulated reflection signals are compared with the measured reflection signal. A location of the fault is located based on the location of the fault for the simulated reflection signal having a highest correlation with the measured reflection signal.
