A Novel Approach for Fault Classification and Fault Phase Selection for Transmission Lines

Abstract: Transmission lines are used to transmit electric power for large distances in electrical power systems. The rapid growth of electrical power systems over the past few decades has resulted in a massive increase of the quantity of lines operative and their total length. These lines are exposed to faults as a result of lightning, short circuits, faulty equipment‟s &human errors. This paper presents a novel approach for fault classification and faulted phase selection for Transmission lines that is dispensed with sequential reactive power components. The proposed technique has been taking a look at about two cases and every case has eighteen test cases from each end. This technique identifies single line to ground fault, double line to ground fault & double line faults for given test case systems and this is implemented using Mat Lab software package.

Keywords: Transmission lines, lightning,s hort circuits, Sequential Reactive power components.
