Abstract
A single-ended traveling wave fault location estimation is calculated using this disclosure, and a confidence level is determined based on available independent fault location estimations. Hypothesis are calculated based on traveling wave times and values, wherein the values indicate a polarity that is the same as the first received traveling wave. Hypothesis are then compared against results of other fault location estimations, and confidence levels assigned accordingly. The fault location is then calculated and displayed based on the hypothesis and confidence levels.
