Things To Know About Arc Flash Analysis

By Dorthy Lloyd


You might not expect about it but arc flash is very hazardous and even cause death to all people around the the workplace. There are some people who are not quite aware of this possibility especially the amount of danger it brings to everyone. Anyone may heard that certain explosions is hotter than the sun's surface. According to studies, electric arc is the hottest on earth next to laser. The point here is that, this phenomenon is very scary and dangerous.

This is the reason why everyone is warned with the impact of the explosion and blast. People know that arc flash is hot and for that reason, employees are all required to wear their protective gear whilst considering the warning labels. To prevent this kind of disaster, it is vital to do an arc flash analysis. Workers are required to undergo training under the supervision of professionals and show positive attitudes towards the practices as well as guidelines in a certain workplace.

Keep in mind that training cannot prevent any possibility of human error. But, there are many things that are in your control and errors are avoidable with consistency.. Those errors will vary depending on your accuracy which will involves other critical details. Aside from that, electrical workers will rarely return to their previous tasks following an arc disaster. They are either maimed, killed or their life is affected.

Potential electrical risks may include electrocution, shock, blast or flash. Usually, electrical risk happens when materials are insulated and no longer containing an applied voltage. A short insulation or circuit can also create a bypass around the circuit. The generated heat by high current flows may also vaporize the material which will create arcs. It will then produce an intense heat, brilliant flash and pressure wave driving the arcing materials.

And because the demand for electric will increase, most transformers at industrial levels can also be upgraded or replaced with the low impedance. Usually, these transformers can be operated at different levels for the achievement of the requirements. These modifications may also cause an increasing fault that will result to electrical energy.

Every employer and employee knows and understands the shock danger but only some know and understand the potential risks. For this reason, analysis is recommended. There are companies that are hiring electrical engineers who are dedicated and committed of keeping their system updated. But, since budget is reduced and the company is downsizing, this function may possibly vanish.

Danger may also happen at no definite time especially when someone is around, walking in the area and when someone is working on the equipment. A risky situation is when someone works near the equipment. This is because, the equipment can be opened, placing workers to danger because of electrical connections, conductors and other components.

The analysis is more than just measuring and calculating the fault current. The analysis usually starts with data gathering and perform a more detailed analysis containing the short circuit, load flow and protective tool coordination studies to determine whether the current rating is acceptable or not.

Knowing the great importance of analysis is helpful for individuals to spread awareness of possible hazards especially if someone has no knowledge and skills about the equipment. This is the reason why professionals are the only one who will handle the job, since they have enough training to do the task.
