In this paper a new method for busbar protection is presented. In this method high frequency components generated by faults in current signals at the outputs of current transformers of substations are extracted by applying TT transform and then the results are processed through the proposed decision rules to discriminate external faults from internal ones. A real 400 kV substation model was simulated in EMTP/ATP-Draw software to evaluate the performance of the proposed algorithm. According to the simulation results, the proposed algorithm has high security and dependability in discrimination of external and internal faults and ultra-fast operation.
