Summary Ark flash analysis essentially means calculating the impact of the electrical backgrounds challenged in open or closed environments on equipment and especially people.The intensity of the energy that will be out of the middle during or near the work is calculated from the tnt type of energy that will occur in the electric panel or in the open shalt fields.According to the arche flash energy account, the personal protective equipment and clothes that must be wearing in this panel or in the field are determined.Again work on this panel according to the arc flash energy account, approach distances are determined.The panels are safe or not, the conformity of the protective equipment used in the panels and systems (cutter, insurance, mcb, tmb, etc.) is also understood by these accounts.The work on the arc flash accounts began to be done in the 1980s because in the 1980s the first time ralph lee developed the open-air arc (open in air arc calculation) calculations that can be used for low voltage facilities, again in the same years the du-pont company has developed a hard-burning product, which is known as the commercial name nomx, the namex, the heat and the fire protection of the electrical equipment, and it has been used for the transportation of a special molecule, the electrical equipment, the electrical equipment, the electrical equipment, the electrical equipment, the electrical equipment, the electrical equipment, the electrical equipment, the electrical equipment, theAfter that, in 1998, three members of the IEEE committee for the first time developed the arc in box calculation.In 2002, the standard to be met in the nfpa electrical studies was published by determining the hazard risk category levels -hrc categories related to the protection from ark flash effects, and in 2012 the nfpa 70e revision added print made it entirely mandatory.Nfpa 70e article 130.3 requires an electrical flash hazard analysis to ensure that employees are properly protected when they work on or near equipment that is not "electrically safe" and that this flash hazard analysis helps ensure the safety of the workers against the dangers associated with the release of the energy caused by an electrical arc.The arche flash accounting procedure is made in accordance with the standard ieee 1584 and any changes, including ieee std 1584a and ieee std 1584b-2011.It is assumed that the equipment in the work is established, operated andined in accordance with the manufacturer's instructions or standards adopted by the industry.Three-phase ac circuits, except the standard 1584 scope, can be analyzed using accepted methods, such as the lee equations defined in ieee 1584.In our country, the effects of the ark flash, the circumstances related to what kind of damage will occur as a result of the ark flash and what kind of measures should be taken in such cases are not so much known.With the growth of our industry and the increased demand for work safety, we are faced with the need to make arche flash analysis calculations in all installations that contain electricity.Electric arc brightness is a serious danger that is likely to result in personnel injury, equipment damage and work loss.In our country, it has been shown that people caused by arrow flush need increased awareness and more education to eliminate or minimize the risk of injury.In our country there is no guide or practical application system for the elimination or minimization of the hazards of arc brightness in the workplaces.There is currently no national standard in this regard.There are numerous technical documents published only by international standards and organizations and equipment manufacturers.However, it requires a consolidated guide with the knowledge and experience of the hazard of the electric arrow and a easy-to-accessful application guide that is easily accessible by everyone.
