What is the function of a capacitive voltage divider in distribution systems?

The function of a capacitive voltage divider in distribution systems is primarily to provide a small, safely measured voltage for metering or analysis. This is achieved by utilizing capacitors arranged in a specific configuration that allows a high voltage from the main distribution system to be reduced to a lower, more manageable voltage level.

This lower voltage can then be used for various applications such as monitoring, metering, or analyzing the electrical system's performance without directly exposing equipment or personnel to the high voltage present in the main distribution lines. The design of a capacitive voltage divider ensures that the output voltage is proportionate to the input voltage while being safe for testing and measurement purposes.

With this understanding, it becomes clear why the other options do not accurately describe the function of a capacitive voltage divider. For instance, while boosting voltage levels might be a concern in other contexts, it is not the primary role of a capacitive voltage divider. Similarly, circuit isolation and energy reduction pertain more to other electrical components or configurations in distribution systems rather than the specific function of a capacitive voltage divider.
