While conducting short-circuit test on a transformer the following side is short circuited

The correct answer is: B. Low voltage side

A short-circuit test is a type of transformer test that is used to determine the transformer’s magnetization current and impedance. The test is performed by short-circuiting the secondary winding of the transformer and applying a voltage to the primary winding. The current that flows through the primary winding is then measured, and the transformer’s magnetization current and impedance can be calculated from this measurement.

The low voltage side of the transformer is short-circuited in a short-circuit test because it is the side of the transformer that has the lower voltage. This is done to minimize the amount of current that flows through the transformer during the test. If the high voltage side of the transformer were short-circuited, the current that would flow through the transformer would be very high, and this could damage the transformer.

The following are brief explanations of each option:

• Option A: High voltage side. The high voltage side of the transformer is the side of the transformer that has the higher voltage. This is the side of the transformer that is connected to the power source.
• Option B: Low voltage side. The low voltage side of the transformer is the side of the transformer that has the lower voltage. This is the side of the transformer that is connected to the load.
• Option C: Primary side. The primary side of the transformer is the side of the transformer that is connected to the power source.
• Option D: Secondary side. The secondary side of the transformer is the side of the transformer that is connected to the load.
