A transformer that is additive in polarity has a coil voltage of what value?

In a transformer, the polarity refers to the manner in which the windings are connected—specifically, whether they share additive or subtractive characteristics. When a transformer is described as having additive polarity, it signifies that the voltages at the terminals of the coils combine positively when measured. This is crucial for ensuring proper phase relationships when multiple transformers are connected in a system.

For additive polarity transformers, the coil voltage can be calculated based on the transformer’s ratings. The choice of 2400 volts is typical for transformers operating in certain distribution systems, particularly in utility applications where voltages must align with standard line voltages to ensure effective service delivery and compatibility with existing electrical infrastructure.

The KVA rating indicates the transformer’s capacity, and while options may vary in KVA ratings, the critical factor tied to additive polarity and usage scenarios relates strongly to the voltage level. In this case, 2400 volts serves as a suitable operational voltage that meets specific system design requirements.

Selecting the answer with 2400 volts reflects the practical voltage used in applicable systems, showcasing a common range that supports infrastructure and serves to align with typical distribution standards.
