What is the MAD at an altitude of 10,152 feet for a 34.5 kV system?

To determine the Minimum Approach Distance (MAD) at an altitude of 10,152 feet for a 34.5 kV system, one must understand that the MAD increases with altitude due to the reduced air density, which affects the dielectric strength of the air. For a voltage of 34.5 kV, standard tables or formulas are typically used to derive MAD values based on the altitude.

At higher elevations, the electrical clearance needed to ensure safety and prevent accidental arcing also increases. Thus, using the specific guidelines for voltage levels and altitude, which indicate the necessary increase in distance to maintain safety, the MAD at 10,152 feet for a 34.5 kV system has been established as 3 feet, 3 inches.

This value takes into account the necessary adjustments in distance due to the unique atmospheric conditions at that elevation, thereby ensuring operational safety when working on or near energized equipment. Understanding this calculation and its importance for safety ensures all personnel are adequately protected against electrical hazards in varying environmental conditions.
