What is the definition of high voltage in electrical terms?

The definition of high voltage in electrical terms is commonly accepted as more than 1000 volts. This threshold is significant because it distinguishes low voltage systems from high voltage systems, which often have different safety protocols, insulation requirements, and regulatory standards.

High voltage can pose serious hazards, including electrocution and arc flash incidents, which necessitate specialized training and equipment for handling. The categorization of voltages is critical in various fields such as electrical engineering, safety management, and emergency response, where understanding and adhering to these definitions ensure the safety of both personnel and equipment.

While different standards may exist globally, and definitions could vary slightly depending on regional codes, the commonly accepted standard aligns with the idea that anything over 1000 volts represents high voltage and requires specific considerations in design and application.
