WebExperiment No: 2 Open circuit and short circuit tests on single phase transformer 1 Aim † To understand the basic working principle of a transformer. † To obtain the equivalent circuit parameters from OC and SC tests, and to estimate e–ciency & regulation at various loads. 2 Theory The physical basis of the transformer is mutual induction between two … 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.
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.
