Classification: CPC G | IPC G

Claim 0:
1. A method for fault detection on an electrical line, the method comprising:
feeding-in a measurement signal at a first location on the line;
reflecting the measurement signal at a reflection location on the line;
receiving the reflected measurement signal at the first location;
determining a fault location on the line based on a time duration until reception of the reflected measurement signal while taking a line attenuation into consideration;
determining the line attenuation based on a level of the reflected measurement signal received at the first location; and
compensating the line attenuation by normalizing the level of the measurement signal reflected from the reflection location to zero decibels, and raising the level of the reflected measurement signal linearly along a length of the line.
