The Value Of Arc Flash Analysis

By Krystal Branch


The use of high voltage poses the danger of electric flashes. This calls for detailed arc flash analysis to establish the potential danger and inform you of the measures that need to be taken in order to prevent disasters. Passing high voltage current through the air occasions blasts which damage equipment and may cause extensive injuries. The temperatures can reach 35000F.

Destruction of equipment and systems results from rapid heating and the extreme pressure that results from the electric blast. It affects the metal conductors along the path of the arc and within the vicinity. The speed of heat in this environment is extremely high and causes rapid expansion. Solid metal conductors are likely to melt in such circumstances causing extensive damage on equipment and the entire 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.

Regulators of the electricity industry require detailed labeling of any environment that is exposed to flashes. Such labeling must indicate the potential so that people in the area can take necessary precautions. For such potential to be indicated, it must be preceded by thorough analysis. Boundaries of such danger should be marked clearly to warn anyone approaching the area. This raises their level of sensitivity and awareness of the possibility of a blast.

Energized electric parts are the sources of arc flashes though there are restrictions on their use by regulatory bodies. Environments where they are found should be clearly marked so that people there are aware of looming danger. Accidents in such areas result from oversight or an error in judgment. Anyone working in such an environment should have protective clothing to minimize danger. The level of exposure varies from one environment to the other. Protective clothing is required when working around charged parts.

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.

Reduction of arch flash energy is possible with the support of experts. It saves expenditure on PPE and reduces the extent of damage. An adjustment on the tripping device is made so that the circuit is broken at lower voltage. This move affects how protective devices are coordinated but it has numerous benefits. Only an expert can effectively carry out the task.

Arc flash analysis is unique for each electric system. Having a detailed report enables you to understand the potential of your system and establish any weak points that need reworking. It raises the level of awareness on potential dangers in work places and therefore reduces the possibility of explosions.
