The Value Of Conducting Arc Flash Analysis

By Krystal Branch


Arc flash analysis is required in all industries where high voltage tools are used in daily operations. It is aimed at reducing the possibility of fire hazards that result from the passage of high voltage current through the air. It causes an explosion that damages the equipment with temperatures that can be as high as 35000 F.

Electric flashes come with explosions that damage equipment and the network. It melts metallic conductors along the path because of the heat that is generated. The heat wave moves fast causing rapid expansion which is a disaster for workers and equipment along its path. These are prefect conditions for starting fires and have been the cause of disasters in many plants and industries.

An environment with high voltage and temperature is dangerous and fatal for the workers. Such instances have caused death or decapitating injuries. The explosion happens within seconds in a way that it cannot be controlled and people within the area have no chance to take cover. The pressure bust is technically equivalent to a combination of dynamite sticks. It is violent and causes definite collapse of systems and huge fires within the premises.

Regulations on electricity use require that areas that are prone to flashes be labeled comprehensively. Their potential should also be clearly indicated so that people working in the area can take caution. Such potential can only be identified if a detailed study is conducted. The danger zones will be marked after a thorough evaluation of the electric systems. Boundaries are clearly marked so that anyone entering or working in the area is sensitive to the possibility of a blast.

All industries or operations dealing with energized electric parts are required to provide personal protection equipment (PPE) to their personnel. Though the law prohibits working with energized tools, it is sometimes inevitable or might happen by mistake. Protecting the workers reduces the severity in case an accident happens. PPE are also selected after a thorough evaluation of the entire electric system.

Failure to maintain electric systems properly raises the level of exposure to danger. Professional installation and constant maintenance are necessary to guarantee safety. A detailed analysis will give you the potential of your system so that adequate measures can be taken to protect those working around. It also will indicate the weaknesses and strengths of such a system and allow you to put in place measures for protection.

There is a way flash arc energy can be reduced in order to scale down the level of PPE required and minimize the possibility of damage. An adjustment may be made on the tripping device for the circuit breaker. The amount of energy during a fault will be reduced. This approach is likely to affect the coordination of the protective devices. This is a delicate and technical assignment that can only be done by specialists.

Each electric system produces a unique arc flash analysis report. There are software used to generate detailed reports which include the strengths and weaknesses of your system. The report gives you a clear picture of the danger that lies within your system so that you can protect yourself.
