This paper presents a fault classification method with faulted phase selection action for single-circuit transmission lines which is based on the symmetrical components of reactive power. The proposed method does not need any threshold to operate and it is thus a setting-free method which is an exceptional attribute for a protective function. The evaluation of different fault cases reveals the capability of the proposed method. © 1986-2012 IEEE.
