This paper comprehensively introduces the basic principle of Mathematical Morphology (MM) and the applications in the field of protective relaying. Two novel morphological filtering techniques are presented, i.e. morphological signal decomposition and multi resolution morphological gradient. The both techniques have been successfully applied in the inrush current identification for transformer protection and transient features recognition for ultra high speed transient protection respectively. The simulation results have proved that the MM filtering techniques have a promising potential in improving the performance of power system protection relays.[KH2D]
