This new FCL is based on series resonance including resonance transformer and series capacitor. So, by proper design of the series resonance LC tank, the fault current is limited to an acceptable level. The FCL operation is simulated using MATLAB software. In order to confirm the simulation results, a prototype structure is built and its measurement results are in agreement with the simulation results. The simulated and experimental results show that it is feasible to develop the FCL with low cost and high reliability.</span></div> <div style="text-align: justify;">This paper proposes a novel Fault Current Limiter (FCL) for the application on distribution networks to control voltage sags at the Point of Common Coupling (PCC) during faults.
