What is "stray voltage," and why is it a concern?

Stray voltage refers to voltage that exists on surfaces such as metal fences, pipelines, or other conductive structures where it is not intended and where such materials are not designed to carry electrical current. This phenomenon often arises from improper grounding, insulation failures, or electromagnetic induction.

The primary concern with stray voltage is that it can create shock hazards for individuals or animals that come into contact with these surfaces. In particular, the presence of voltage on surfaces can put workers, bystanders, and animals at risk of electric shock, even if they are not directly involved with electrical equipment.

Understanding the origin and implications of stray voltage is crucial for ensuring safety in environments where electrical equipment is in use. It necessitates careful monitoring and maintenance of electrical systems to minimize any risk of unwanted voltage manifesting in unintended areas. Additionally, addressing stray voltage helps uphold electrical system integrity and public safety.
