A three-phase transformer connection has a delta-connected secondary, and one of the transformers has been center-tapped to form a neutral conductor. The phase-to-neutral value of the center-tapped secondary winding is 120V. If the high leg is connected to a single-phase load, how much voltage will be applied to that load

Answer:

207.84 V will be applied to that load.

Explanation:

Given that;

The phase-to-neutral value of the center-tapped secondary winding is 120V

the high leg is connected to a single-phase load

voltage that will be applied to that load = ?

Now, the the high leg voltage will be 1.732 times the single phase center tapped voltage .

so

Load Voltage = 1.732 × 120V

Load Voltage = 207.84 V

Therefore, 207.84 V will be applied to that load.
