What is an essential consideration when determining MAD for power systems?

When determining the Minimum Allowable Distance (MAD) for power systems, altitude is an essential consideration due to its impact on electrical performance and safety. Higher altitudes can lead to decreased air density, which affects the dielectric strength of air. This reduced dielectric strength means that air can become ionized more easily, which may lead to electrical arcing or short circuits if equipment or conductors are placed too close together. Thus, MAD calculations must account for altitude to ensure that appropriate distances are maintained between electrical components to prevent failures and ensure safe operations in power systems.

The other factors, while they may have their own relevance in specific contexts, do not directly influence the fundamental principles of MAD in the way altitude does. Weather conditions, time of day, and type of equipment used may affect operational parameters and performance but are not primary determinants in calculating safe distances for electrical safety.
