The electronics arc is a dangerous phenomena that occurs in electrical systems when there is an interruption in the continuity of the external phase or phase. It initially manifests itself as a luminous flash and a sudden release of energy called the "arc late". This arc relaxation is the initial and most intense stage of the electric arc, releasing a large amount of energy in the form of heat, light, ultrared.
This phenomena occurs at an extremely fast speed, almost at the speed of light, and can generate a significant amount of heat in the form of heat per square centimeter. This energy is released in the form of an incandescent layer, composed of radiant heat, visible light and ultraviolet light. The amount of heat released may vary depending on specific electrical equipment and the circumstances of failure.
Once the arc delay occurs, there is a sharp rise in temperature in the materials that make up the electrical equipment. These materials can go through different states, such as sublimation of subsctions to vapours, formation of lines and plasma, and the release of fragments. This results in a number of destructive effects, including high-intensity noise generation, high pressure and hot and molten parts.
The rapid expansion of gas and hot air creates a shock wave or arc burst that travels at the speed of sound. This arc burst emits a high level of decibels and can project molten metal and plastic parts at high speed. The expansive wave and fragments can cause physical damage and injury to people near the electronics arch.
