Abstract
This paper presents a new approach to protect the transmission line by a design and implementation of distance relay using Fuzzy logic module. The proposed module uses sample of voltage and current signals to calculate line impedance (ZL). Simulation studies are performed and influence of changing system parameters such as type of faults like single line to ground fault, three phase to ground fault and double line to ground fault, also fault resistance and fault location; were taken the results show that the module respond in a very high speed relay, the performance of this distance relay is fast and accurate as compared with other relays the detection is with in less than 1⁄8 of the period.
