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 ... curling from olds

WebThe two parameters which can be calculated from the open circuit test of transformer are R o and X o. They are calculated as follows. Step 1: Calculate no load power factor (cos φ o) The wattmeter reads the real power input. Therefore, W o = V oIo cos φ o. or cosφ o = W o /V oIo. We can calculate φ o from this. Step 2: Calculate Im and Iw :

The open-circuit test, or no-load test, is one of the methods used in electrical engineering to determine the no-load impedance in the excitation branch of a transformer. The no load is represented by the open circuit, which is represented on the right side of the figure as the "hole" or incomplete part of the circuit.

WebNo-Load test or Open-Circuit Test: The no-load test of an induction motor is similar to the open-circuit test of a transformer. The motor is not connected from its load, and the rated voltage at the rated frequency is applied to the stator to run the motor without a load. The 2-wattmeter method measures the input power of the system.
