Abstract: The key challenge to the cable protection lies in faithfully police work and uninflected faults compromising the protection of the system. during this paper reciprocal ohm Characteristics and Frequency Dependent (Phase) model sort cable square measure modelled and simulated victimisation PSCAD/EMTDC package. a quick Fourier remodel block in PSCAD/EMTDC has been accustomed extract the basic part. Unsymmetrical and symmetrical faults at totally different zones were performed to review the performance of the relay characteristics and to research the consistency of the relay models generated with the planned methodology. The network utilized in this paper is 230kv systems.
