This paper will discuss and model the characteristics of the Mho relay and impedance Relay Characteristics.Modelling of Protective Relay offer an economical and feasible alternative to investigate the performance of relay andprotection systems. In this paper Mho and Impedance relay characteristics type Protection system are modelled andsimulated suing PSCAD/EMTDC Software. To study the performance of the relay characteristics, different type of faults(L-G, L-L, L-L-G etc.) at different locations are considered. Here the comparison of the relay characteristics under faultresistance is considered. Fast Fourier Transform (FFT) Block is used to extract the Fundamental component of theFrequency. In this paper the 220KV transmission line is modelled.
