AVO Substation Maintenance II Practice Test 2026 - Free Practice Questions and Study Guide

High humidity can significantly impact substation equipment by leading to corrosion and eventual failure. When moisture levels are high, it creates an environment conducive to the formation of rust and corrosion on metal components. This deterioration not only compromises the structural integrity of the equipment but can also interfere with electrical connections and performance.

Corrosive environments may accelerate wear and tear, potentially leading to short circuits or operational failures. Additionally, moisture can impact insulation materials, reducing their effectiveness, which is critical for maintaining the reliability and safety of electrical systems. Thus, understanding the relationship between high humidity and equipment health is essential for maintaining the longevity and functionality of substation components.
