At what voltage level are voltages classified as experimental voltages?

Voltages classified as experimental voltages typically refer to extremely high voltage levels that are not commonly used in standard electrical applications or infrastructures. These levels are often used in research and testing environments to explore the behavior of materials and components under extreme conditions.

In this context, 1 million volts is recognized as the threshold for classifying voltages as experimental due to several factors. At this level, unique phenomena related to electrical conduction, dielectric breakdown, and insulation are observed, which do not occur at lower voltages. These experimental voltages allow researchers to investigate advanced applications such as high-voltage transmission, particle acceleration, and the effects of electric fields on different materials.

The other voltage levels, while high, fall short of marking the transition into the specialized realm of experimental voltages. Below 1 million volts, applications tend to align more with established industry standards and practices, making them less experimental in nature.
