The global market for Arc Flash Protection is projected to reach US$2.4 billion by 2025, driven by the ever-present threat of arc flash hazards in virtually every industrial environment ranging from utilities, manufacturing and processing, oil & gas to transportation and infrastructure. The ever-present threat of arc flashes can be out into perspective by the fact that virtually all electrical systems of voltages 200V or greater are susceptible to arc flash incidents. The addressable market opportunity can also be measured by the growing use of electrical enclosures against the backdrop of massive quantities of electricity produced and consumed worldwide coupled with the ubiquity of power electronics. Arc flash is an electrical explosion of light and heat caused when stray electric current flows through air gaps between conductors. Causes of arc flash accidents include gaps in electrical insulation; improper installation; use of non-standard and/or sub-standard electrical parts; accumulation of corrosion, dust on the surface of the conductor; worn-out conductor insulation; loose wire connections; obstructed disconnect panels;  and improperly maintained switches and circuit breakers. All of these factors trigger faulty current magnetic fields by abnormal conduction of electrical current from phase to ground, phase to neutral, and/or phase to phase and when ionized by surrounding air results in an explosion. Arc faults are extremely hazardous to personnel and the enormous energy and heat released by the explosion can result in severe skin burns. Heat released by the arc can reach 40,000 degrees Fahrenheit, temperatures over 4 times higher than the temperature of the sun’s surface, making the explosion fatal for people and equipment. The high intensity flash can also damage the eyes and cause permanent loss of vision, while the shock waves caused by the explosion can knock down people and walls. The sound of the explosion can rupture eardrums and cause hearing loss. Read More…

  1. Hey there! I recently visited an incredible hearing aid service center and had an experience that I just have to share. If you're dealing with hearing issues and are considering a hearing aid, you need to check this place out. The team was super friendly and professional, making me feel comfortable from the start. They conducted a thorough hearing evaluation and provided me with a variety of options tailored to my specific needs. Their range of hearing devices is second to none, offering the latest technology for clear and natural sound. If you're thinking about getting a hearing aid, I highly recommend visiting them—you won't regret it! For more info, click here.
