This test results the iron losses and no load current values, thereby we can determine the no load branch parameters with simple calculations.Īs the name itself indicates, secondary side load terminals of the transformer are kept open and the input voltage is applied on the primary side. This test is performed to find out the shunt or no load branch parameters of equivalent circuit of a transformer. Open Circuit or No Load Test on Transformer ![]() This tutorial enumerates how to perform these tests, how determine the equivalent parameters from test data and significance HV or LV side in which the calculation to be performed. This method of finding the parameters of a transformer is called as an Indirect Loading Method. Without actually loading the transformer, these two assessed tests give the test results, which are used to determine the equivalent circuit parameters.īy these parameters, we can easily predetermine the efficiency and regulation of the transformer at any power factor condition as well as at any load condition. These circuit parameters are supplied in terms Open Circuit (OC) and Short Circuit (SC) test data of a transformer. It is possible to predict the performance of a transformer at various levels of load by knowing all the equivalent circuit parameters. Open Circuit or No Load Test on Transformer.
