The fault current limiter is one of the important means to solve this problem of excessive short-circuit current. The use of high coupled spilt reactor (HCSR) to achieve limit and interruption of fault circuit current (FCL) is a new technique in recent years. The distributions of fault current on current-sharing state and voltage inside the FCL on current-limiting state are verified through the small prototype test in this article. The test results show that the input of the arc resistance will cause the current difference of the two parallel branches of the FCL. After analysis, it is found that this difference is proportional to the single-arm inductance of HCSR, so it will be small when applied to high current, and will not affect the current sharing of the two branches. Besides, the difference of the voltages of two vacuum breakers and the appearance of DC voltage between the branches at the end of the HCSR are related to the value of current-chopping, which can be ignored in the high-current situation. The phenomenon different from the ideal simulation during the test is analyzed to verify the feasibility of the FCL topology based on HCSR in actual operation.
