What would likely be the effect of high voltage on the performance of electrical equipment connected to running rails?

High voltage can exert significant stress on electrical equipment connected to running rails, leading to overheating and potential damage. This occurs because electrical components are designed to operate within specific voltage ranges. When subjected to high voltage, these components may experience excessive current flow, generating heat due to increased resistance in their circuits.

Overheating is a critical concern, as it can compromise the integrity of the materials within the equipment, causing insulation breakdown and leading to failures. Prolonged exposure to high voltage conditions can reduce the lifespan of the equipment and may result in catastrophic failures, necessitating costly repairs or replacements.

Understanding the impacts of high voltage is essential for maintaining operational safety and ensuring the reliability of electrical systems associated with running rails. Thus, the connection between high voltage and the risk of overheating and damage is direct and significant.
