The magnetizing loss is about the same in both tests, but it is relatively small when compared to 100x the copper loss so it is much easier to measure in the open circuit case, and there is nothing to be gained from measuring it twice.

WebWhat are open and short circuit parameters? The open circuit and short circuit tests are used to determine the transformer's efficiency, voltage regulation, and circuit constant, among other things. Because these tests are carried out without any actual loading, relatively little electricity is required for the test. Webchapter2ECEg-3131_transformers - View presentation slides online.

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. WebThe purpose of the open-circuit test is to determine the no-load current and losses of the transformer because of which their no-load parameters are determined. This test is performed on the primary winding of the transformer. The wattmeter, ammeter and the voltage are connected to their primary winding. The nominal rated voltage is supplied to ...
