Protection of Distributed Generation (DG) is a challenging task in entire electrical family. DG plays a vital role in advanced power systems engineering. The connection of DG to the distribution network has numerous advantages. Even though it has a advantages, while connecting the DG with existing power system network, the fault current level in many places have often exceeded which causes the abnormal conditions in the entire power system network. In order to reduce the fault current level, various Fault Current Limiters (FCL) are proposed. In this paper hybrid Fault Current Limiter (HFCL) and its applications are proposed to minimize the effect of the DG on the distribution protection system in a radial system during a fault. The simulated results are analysed and compared with a Solid State Fault Current Limiter (SSFCL) and Superconducting Fault Current Limiter (SFCL) using MATLAB simulation. The effectiveness of proposed fault current limiters are determined and examined in the test system.
