Which voltage system at 7,450 feet results in an MAD of approximately 2 feet, 5 inches?

The correct choice is based on the concept of voltage drop and the Maximum Allowable Drop (MAD) related to different voltage levels over a specified distance and elevation. At 7,450 feet, the atmospheric conditions become more challenging, impacting the electrical system’s performance.

Choosing a voltage system that yields an appropriate MAD at this elevation is crucial for maintaining efficient operation and safety. The 4.16 kV system is designed to deliver power effectively while allowing for a controlled voltage drop within the desired limits at this altitude. It allows for sufficient voltage regulation over long distances, ensuring that the drop does not exceed approximately 2 feet, 5 inches. This is particularly important to avoid issues such as equipment malfunctions or inefficiencies in power distribution.

Higher voltage systems, like 15 kV or 34.5 kV, while capable of carrying power over long distances, typically do not have the same corresponding MAD values at these altitudes. They are designed for longer transmission segments, which can inadvertently increase voltage drop beyond acceptable levels in certain applications. Conversely, lower voltage systems, such as 2.4 kV, might not be suitable at such heights for the same reasons, resulting in a larger MAD that exceeds the specified measurement. Thus, a
