Stray current

Stray current, in the context of electrical engineering, refers to an unintended flow of electric current through conductive paths other than the intended circuit. This phenomenon can occur in various systems, such as railways, pipelines, or utility grids, where electrical currents inadvertently stray from their designated paths. Stray currents can lead to corrosion and damage to metal structures, particularly in underground or submerged environments. Managing and mitigating stray currents is crucial to prevent the detrimental effects they can have on infrastructure, ensuring the safe and efficient operation of electrical systems and minimizing the risk of corrosion-related issues in affected structures.
