Abstract

A method for detecting faults on an electrical line includes feeding a measurement signal to a first location on the line by using a measuring assembly, receiving a reflected measurement signal at the first location, and determining a fault location on the line on the basis of the period of time until the reflected measurement signal is received while considering a line attenuation. A reflection location on the line where the measurement signal is reflected is used, and the line attenuation is determined on the basis of the level of the reflected measurement signal received at the first location. A corresponding measuring assembly is also provided.
