Due to Arc Fault, the massive energy Released – Arc Blast is created due to blasting molten metal and expanding plasma inside of the ASSEMBLY with extraordinary force, which Damages the Assembly and throws not only metals pats, doors but can also blow worker away from the Arc. This Blow of worker may be more severe than Arc Burn.
| Overpressure | Wind Speed | Effects on Structures | Effects on Human Body |
|---|---|---|---|
| 1 psi | 60 kmph | Following may Break/Shatter : Panel glass doors, LCD Glass of Meters or Switchgear, Panel Room Window glass |
Minor injuries to human body may happen due to Glass break/shatter. |
| 2 psi | 110 kmph | Moderate damage to Switchboard Assembly and Panel Room may happen. |
Major injuries to Human body, due to flying debris may happen. |
| 3 psi | 160 kmph | Switchboard Assembly may Collapse And Panel Room Structure may also get collapse. |
Major injuries to Human body will be obvious, and fatalities are likely. |
| 5 psi | 260 kmph | Panel Room and Building Structure may Collapse. |
Fatalities are likely in the Panel room. |
| 10 psi | 470 kmph | Reinforced concrete building may get damaged. |
Fatalities are likely beyond Panel room, near by room and Structures. |
| 20 psi | 800 kmph | Heavily built Reinforced concrete Building may get demolished. |
Fatalities are likely in the entire Building Structure. |
Psi is pounds of force per square inch area.
1 pound = 0.454 kg
1 inch = 2.54cm
1 psi = Pressure due to Weight of 1 pound/0.454 kg on 1 inch2 / 2.54 cm2 of area.
1 psi = 6894 N/m2
1 psi = 0.068 atmosphere
Arc Blast is the supersonic shockwave produced when the uncontrolled Arc vaporizes the metal conductors.
The massive energy released in the Arc fault rapidly vaporizes the metal conductors involved, blasting molten metal and expanding plasma inside of the ASSEMBLY with extraordinary force, which Damages the Assembly and throws metals pats, doors, this can be big damage for Asset Protection and Employee Protection.
After the Arc Blast, Metal vapors while cooling down becomes oxide of the metal of the arc, during this minute particles appars like smoke.
Color of this Metal Vapor/Smoke will be as follows :
Iron: Black.
Copper: Black.
Aluminum : Grey.
