While conducting open circuit test and short circuit test on a transfo...
For transformer testing:




  • Open Circuit (OC) Test:



    • This test is used to determine the core losses and no-load characteristics of the transformer. In this test, the high-voltage (HV) winding is energized, and the low-voltage (LV) winding is kept open.




  • Short Circuit (SC) Test:



    • This test is used to measure the copper losses and the impedance of the transformer. In this test, the low-voltage (LV) winding is short-circuited, and the high-voltage (HV) winding is energized.





So, the correct configuration is:


2. OC test – l.v. open, SC test – h.v. short-circuited

While conducting sc test hv wdg will be short ckted & for oc test lv wdg will be open ckted.because open ckt test conduct to measure core or iron loss if take it on hv wdg it will drop more power and copper loss so OC test conducted on lv side and sc test on hv side .

In the open circuit (OC) test, the low-voltage winding will be connected to the power supply while the high-voltage winding will be left open or disconnected. This is done to measure the no-load current and losses in the transformer.

b) SC test

In the short circuit (SC) test, the low-voltage winding will be shorted or connected to a low impedance load, while the high-voltage winding will be connected to the power supply. This is done to measure the short circuit current and losses in the transformer.
