Abstract
A system for detecting a location of fault in a cable includes a cable transmitting a fault current, a current transforming unit connected to the cable and receiving the fault current and detecting an original signal of fault current, a detecting unit detecting a first detail signal and a second detail signal from the original signal of fault current, where both signals are detail components in a high frequency band, a comparing unit comparing the first detail signal with a preset reference value and determining a fault in the cable, and a signal filtering unit generating a first filtering signal and a second filtering signal by use of the first detail signal and the second detail signal and outputting a fault detection signal based on a result of comparing both signals.
