This transformer, when banked and connected delta on the low side, would yield which of the following system voltages?

To understand why the system voltage yields 2400 3-phase 3-wire when the transformer is banked and connected delta on the low side, it's essential to consider how voltage transformation works in various configurations and what the typical low-side voltages are.

In a three-phase transformer system, the low side of the transformer typically corresponds to lower voltage ratings used in distribution systems. When a transformer is configured in a delta connection on the low side, it can handle unbalanced loads more effectively and allows for secure grounding practices.

For a standard distribution setup, a common low-side voltage rating in many utility systems is 2400 volts when configured as a 3-phase, 3-wire system. This configuration is commonly used in rural and suburban areas for medium-voltage applications where the loads are not excessively high.

The other options provided correspond to higher voltage levels that are either less common for low-side delta connections or represent different configurations (like 4-wire systems). For example, 4800 volts and 4160 volts are also used in specific industrial applications but typically represent higher voltage systems or are associated with more complex wiring arrangements such as a 4-wire system which includes a neutral conductor.

By ensuring that the transformer is correctly connected in the delta configuration and
