Conventional Non-Loss Fault Current Limiters(NLFCL) cannot restrain the short-circuit current of the maximum peak at all fault phase angles in 10 kV distribution network, due to which, the protection of impacting damage is not effective. In order to solve above the problem, a light loss fault current limitation technology is proposed, in which, a fast switch is only paralleled with a certain proportion of the Current-Limiting Reactor (CLR), it can restrain the maximum short-circuit current and reduce the operation loss. The way to obtain the best proportion of the CLR paralleled with the fast switch is described, in which, the peak of the maximum short-circuit current, the duration time of the current exceeding the allowed value, the loss and the voltage drop in normal operation are taken as evaluation indexes. Combined with typical application scenarios, the fault current limitation effects of Light Loss Fault Current Limiter (LLFCL) with natural arc-extinguishing and artificial arc-extinguishing are analyzed in comparison with NLFCL at various fault phase angles. The results of the analysis show that the proposed LLFCL is feasible which can effectively limit the maximum fault current.
