Abstract
A method and apparatus for fault identification in a transmission line are provided. The method may include measuring at an end of the transmission line when the transmission line has a fault to obtain a measured signal, comparing the measured signal with a predefined standard signal, the predefined standard signal having beat frequency characteristic; and identifying that the fault is a transient fault if the measured signal matches the predefined standard signal according to a result of the comparison, or the fault is a permanent fault if the measured signal does not match the predefined standard signal according to the result of the comparison.
