  • Dielectric gas - Wikipedia

    A dielectric gas, or insulating gas, is a dielectric material in gaseous state. Its main purpose is to prevent or rapidly quench electric discharges . Dielectric gases are used as electrical insulators in high voltage applications, e.g. transformers , circuit breakers (namely sulfur hexafluoride circuit breakers ), switchgear (namely high voltage switchgear ), radar waveguides , etc.

    Notes 1. A lightning strike may commence at around 10 2 to 10 6 Volts (1000 kV) between the clouds and the ground. By the time it reaches the ground, it loses a part of its intensity. Although it may still be around 1000 kV at ground level, it is possible that sometimes switching surges at an EHV system above 245kV are more severe than a lightning surge, the more so because the amplitude of a

    An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator have tightly bound electrons whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.This contrasts with other materials, semiconductors and conductors, which conduct an electric current more easily.
