*Abstract

With the increase in demand for electrical power, the undesirable fault current in the power system has correspondingly increased. In prior art, many fault current limiters (FCL)/technologies have been used to address this issue. However, these approaches are associated with possible limitations. For example, high operational losses with extra energy requirements in the case of superconductor FCLs (SCFCL) and solid-state FCLs (SSFCL), bulkiness of systems, and frequent servicing or parts replacement requirement in the case of and Is-limiter. This novel approach comprises the development and use of a non-superconducting fault current limiting (NSCFCL) system to control the fault current in a power system.
