How are taps determined in a transformer?

Taps on a transformer are used to adjust the voltage output to meet specific requirements. The correct method to determine the required tap settings involves understanding the relationship between the actual voltage and the desired voltage.

In this context, the calculation comes down to determining how much of the transformer's voltage can be utilized to achieve the desired output. By dividing the actual voltage by the desired voltage, you can determine the appropriate ratio to set the taps correctly. This calculation helps ensure that the transformer operates at the correct voltage according to the load requirements.

Using this method ensures that the output voltage is transformed appropriately according to the needs of the electrical system. It takes into consideration the characteristics of the transformer and optimizes its performance for specific applications, thus maximizing efficiency and minimizing losses.

The other methods listed do not accurately reflect how taps are determined in a transformer, whether by multiplying, adding, or trying to transform the voltage directly without addressing the ratio of actual to desired voltage.
