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.

Extreme pressure and rapid heating leads to destruction of electric systems and equipment. All metal conductors that are along the path of this electric current are affected. Rapid expansion and fast moving heat wave are disastrous to workers and equipment along the path. Metal conductors along the path of the heat and electric current will melt. There is a high possibility of igniting fire which would destroy the premises.

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.

An analysis is required for any industry or plant where energized electric parts are used. Workers should have personal protection equipment (PPE) before entering into these zones. The law restricts operating energized tools but most of the mistakes arise from oversight and unintended errors. Workers who are adequately protected will be exposed to less danger. Each environment requires unique PPE. To master the kind of protection required, you need to understand the potential of your system.

If electric systems are not adequately maintained, they are vulnerable to explosions. The safety of a system is guaranteed from installation. Knowing the real potential of the system means you can take adequate precautions. Under protection exposes workers to risky currents and blasts. The analysis conducted helps you to grasp the strength and weakness of your system.

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.

The report from arc flash analysis offers unique details for each system. It gives you a thorough understanding of your potential and possible weaknesses. You understand the dangers you are exposed to in order to take precaution.
