PURPOSE:To enable the simulating of characteristic of a transformer with relative ease, by adjusting a means for generating a magnetic flux/voltage generation component with an adjustment means. CONSTITUTION:With a short-circuiting between terminals 61 and 62, the simulation of primary leakage impedance is performed for a transformer. In other words, the input/output side of a transformer 14 is adjusted to compensate for a drop in the voltage due to a resistance 11 so that the ratio between a primary winding resistance and a primary leakage reactance is the same as that with an actual equipment as viewed from a primary terminal 1. As for secondary leakage impedance of a transformer, an input and output of a transformer 24 is adjusted so that the ratio between a secondary winding resistance and a secondary leakage reactance is the same as that with an actual equipment as viewed from a secondary terminal 2. Then, terminals 63 and 64 are opened to adjust an input of a winding 31, thickness of a core in a magnetization characteristic simulation circuit 3 and the like so that a voltage drop generated at the terminal 1 and an inflow current are in a characteristic relationship similar to that of an actual equipment. Moreover, the terminals 61 and 62 are opened to adjust an input of a winding 32 so that a voltage drop generated in the terminal 2 and an inflow current are in a characteristic relationship similar to that of an actual equipment. This facilitates the simulation of electric characteristic of the transformer.
