Awareness of the dangers of arc flashes and the need to protect your team with specialized arc flash protection is more important today than ever before. Awareness of arc flash protection will increase as you become more aware of the dangers an arc flash incident can pose.
A fundamental aspect of your job is to understand how to mitigate these risks, whether you work in the electrical industry, power generation or petrochemicals, whether you work for a utility company or perform work on the railway.
Reducing risks through safe work practices and providing appropriate protective clothing that offers excellent protection against arc flashes saves lives every day.
Was ist ein Störlichtbogen?
An arc flash occurs when an electrical discharge moves through the air, releasing an intense burst of energy. This lightning can seriously injure anyone caught in it, which is why proper arc flash protection is of utmost importance.
The energy released during an arc flash can be lethal, reaching temperatures as high as 35,000ºF or more than 19,000ºC. Needless to say, this can cause burns to clothing and human skin within a fraction of a second, even if the worker is five or six meters away from the arc.
The cause of an arc flash is usually contact between a live conductor, such as a busbar or wire, and another conductor or a grounded surface. This can occur due to equipment failure, uninsulated tools, or damaged wiring. Although high-voltage systems are often assumed to be more prone to arc flashes, studies have shown that low-voltage systems can be just as, if not more, dangerous. Variables such as current flow, the size of the gap between conductors, the composition of the electrodes, and environmental factors all influence the severity of the arc flash.
