Abstract: Transmission lines are one of the most important components of electrical power systems, and proper protection is necessary to maintain system stability and reliability during fault conditions. This research work presents a comparative study and MATLAB/Simulink-based analysis of distance protection for transmission lines using Impedance, Reactance, and Mho relays. The proposed system continuously monitors transmission line voltage and current values using Current Transformers (CT) and Potential Transformers (PT). Based on these electrical parameters, the relay calculates impedance values to detect and isolate faults occurring on the transmission line. Different fault conditions such as line-to-ground, line-to-line, and three-phase faults are simulated and analyzed under varying operating conditions. The performance of Impedance, Reactance, and Mho relays is compared based on response time, sensitivity, stability, and directional characteristics. Simulation results show that the Mho relay provides improved directional protection and system stability, while the Reactance relay performs effectively during high resistance fault conditions. The proposed system improves transmission line protection reliability, minimizes equipment damage, reduces power interruptions, and enhances overall power system performance.
