Abstract

A novel power distribution line fault locating system is provided herein. The system includes at least one first data manipulation unit for manipulating conducted fault signal data resulting from a fault on a power distribution line, and producing and communicating a first set of fault location data. At least one second data manipulation unit is provided for manipulating electromagnetic radiated signal data emanating from the fault on the power distribution line, and producing and communicating a second set of fault location data. A fault location centre is responsive to the first set of fault location data and to the second set of fault location data which is produced by the at least one first data manipulation unit and the at least one second data manipulation unit, for determining a location of the fault.
