Abstract: For the coupling transformer in the new bridgetype solid satae fault current iimiter(SSFCL), an analysis and design method were proposed. The finite element analysis (FEA) method of magneticcircuit coupled field could analyse the transformers running characteristic accurately. The design methed based on the principle of variable impedance transformer, at the same time the coupling transformer had the current limiters function. So that the size and cost of the whole current limiter system and the transformer could be reduced greatly, and it has good application prospect。
