PROBLEM TO BE SOLVED: To provide a simulation iron core which can be applied to tests for checking the quality of substitute windings having various diameters and lengths, and a method for checking the quality of a substitute winding using the same.SOLUTION: The simulation iron core used for a substitute winding quality check test includes: simulation iron core legs 2; and upper and lower simulation yokes 3 and 4. In the simulation iron core, bonding planes between the simulation iron core legs 2 and the upper and lower simulation yokes 3 and 4 are all parallel with each other, and the simulation iron core legs 2 can be moved in a longitudinal direction of the upper and lower simulation yokes 3 and 4. The size between the adjacent simulation iron core legs 2 and 2 is adjusted to the size between iron core legs of a transformer with a winding which needs renewing by appropriately moving the simulation iron core legs 2 in the longitudinal direction of the upper and lower simulation yokes 3 and 4, and then a test for checking the quality of a substitute winding is performed.
