What is high voltage as per IEC?

High voltage is a term commonly used in the field of electrical engineering to denote the presence of a voltage level that is significantly higher than the normal operating voltage. International Electrotechnical Commission (IEC) is an organization that sets international standards for various aspects of electrical and electronic technologies, including high voltage levels.

Understanding voltage levels

Voltage is a measure of electric potential difference between two points in an electrical circuit. It is often measured in volts (V). According to IEC standards, high voltage is typically defined as any voltage level above 1000 volts (1 kV). However, there are different classification schemes based on application areas, and some may consider voltages above 35 kV as high voltage in specific contexts.

Importance of high voltage safety

Working with high voltage systems carries significant risks, as exposure to high voltage can cause electric shock, burns, and other serious injuries or fatalities. Therefore, ensuring safety is of utmost importance when dealing with high voltage equipment. IEC standards play a crucial role in defining safety measures and guidelines for high voltage systems to minimize such risks and protect both personnel and equipment.

Applications of high voltage

High voltage is utilized in various applications across different industries. Some common examples include power transmission and distribution systems, electrical motors, transformers, generators, and industrial processes that require high electrical energy. These applications often require special equipment and precautions due to the high levels of electrical energy involved.
