Web1 Answer. Under open circuit test, in a sense, the transformer is no longer a transformer, but a pure inductor. The inductance is proportional to the N^2. So measuring from primary side (higher voltage and higher N in your case), you will see higher inductance, less magnetizing current. From the other side, you will get less inductance and ...
