Fault location system and method for distribution network

摘要

A fault location system 18 for a distribution network 10 is disclosed. The fault location system 18 includes at least one sensor 11, 12 and a fault location evaluation apparatus 19. The at least one sensor 11, 12 is located on the distribution network 10, for sensing current and dividing the distribution network 10 into at least two regions. The fault location evaluation apparatus 19 includes a fault region determination unit 191 for determining which one of the at least two regions is a fault region where a fault occurs therein by calculating the sensed current from the at least one sensor 11, 12.
