The objective of this paper is to determine the impact of the Hybrid superconducting fault current limiter (HSFCL) on transmission lines distance protection for line to ground and line to line fault. The MATLAB software is being used to simulate transmission system with distance relay protection along with Hybrid superconducting fault current limiter (HSFCL). The parameters included in the simulation studies are fault type and fault location. Mostly in context of line to ground and line to line faults, this paper explores the impact of HSFCL on measured impedance at the relaying point. Its installation position, in addition to the degree of constraint, has an impact on the measured impedance. In all situations, the collected research suggests that HSFCL has a negative impact on distance relay performance. The influence of both configurations of Hybrid superconducting fault current limiter (HSFCL) i.e. Resistive and Inductive over distance relay protection for line to ground and line to line faults are to be analyzed and compared.
