A short circuit test on a transformer gives ___________.a)copper loss ...
From the short circuit test of the Transformer we will find out full load copper loss and equivalent circuit parameter & voltage regulation.
From full load copper loss we can find out copper losses at any fraction of load by using the following formula.
Wcu at x% full load = x2 [Wcu full load]
From full load copper loss we can find out copper losses at any fraction of load by using the following formula.
Wcu at x% full load = x2 [Wcu full load]

Short Circuit Test on Transformer
A short circuit test is performed on a transformer to determine the copper loss in the transformer. This test is also known as the impedance test or the locked rotor test. The test is performed by short-circuiting the secondary winding of the transformer, and then applying a reduced voltage to the primary winding.
Purpose of Short Circuit Test
The purpose of the short circuit test is to determine the copper loss that occurs in the transformer when it is operating at full load. This test is performed at a reduced voltage, and the current that flows through the transformer is measured. From the measured current and the applied voltage, the copper loss in the transformer can be calculated.
Copper Loss Calculation
The copper loss in the transformer can be calculated using the following formula:
Copper Loss = I^2R
Where I is the current that flows through the transformer during the short circuit test, and R is the resistance of the transformer windings.
Copper Loss at Any Load
Since the short circuit test is performed at a reduced voltage, the copper loss calculated from this test represents the copper loss that occurs in the transformer at any load. Therefore, the answer to the given question is option B, which states that a short circuit test on a transformer gives the copper loss at any load.
Conclusion
In conclusion, the short circuit test is an important test that is performed on transformers to determine the copper loss that occurs in the transformer at any load. This test helps in determining the efficiency of the transformer, and is essential for the proper functioning of the transformer.
