REFERENCES 1 Keeping design principle in mind the parameter of transformer was obtained by open circuit and short circuit tests, without actually loading the transformer, and these two assessed tests give the test results which are used to determine the equivalent circuit parameters Open circuit test or no load test on a transformer is performed to determine 'no load loss (core loss)' and 'no load current I'. The circuit diagram for open circuit test is shown in the figure below † To obtain the equivalent circuit parameters from OC and SC tests, and to estimate e–ciency & regulation at various loadsTheory In this article, learn how to analyze the results of open-circuit and short-circuit transformer tests to determine the component values of the transformer equivalent circuit. From these tests, it is possible to determine the equivalent circuit of the transformer. Evaluate the regulation and efficiency of the transformer at a given load. The experiment also studies the excitation current, magnetization current, and core-loss current. In this article, in addition to the tests mentioned in the title, we will also discuss the polarity test and Sumpner’s test demonstrates the concept of open-circuit and short-circuit testing of transformers. (b) To perform short circuit test on the Open circuit test and short circuit test are conducted to determine the core loss, copper loss, and equivalent circuit parameters of a transformer Open Circuit (No Load) and Short Circuit (On-Load) Test of a Transformer. To find out the parameters of transformer, we perform the open-circuit and short-circuit tests on transformer. To conduct standard open and short circuit tests in order to find the parameters of the equivalent circuit of a transformer. Evaluate the regulation and efficiency of the Open Circuit Test The purpose of the open circuit test is to determine the no-load current and losses of the transformer because of which their no-load parameter are determined OPEN-CIRCUIT AND SHORT-CIRCUIT TESTS ON TRANSFORMER. In this method, the actual load is not used on transformer. As we have seen in the equivalent circuit of transformer, there are four main parameters; The open Open circuit and short circuit tests on single phase transformerAim † To understand the basic working principle of a transformer.
