The Importance Of Arc Flash Analysis

By Dorthy Lloyd


You might not think about it, but arc flash is dangerous and may cause death to employees. No one is working in the industry that is not aware of this kind of danger. Everyone heard that any explosions is hotter than the usual heat you may experience under the sun. In fact, according to research, electric arc is the hottest even on the planet next to the laser. At some point, it is scary.

This is the main reasons why individuals are given some warnings on the effects of the explosion or blast. Everyone understands that arc flash is very hot. Therefore, employees should wear protective clothing and gear while observing the proper warning labels. To prevent such disaster, b it is crucial to consider the arc flash analysis. Every employee also need to undergo training along with proper supervision and attitude towards the practice and guidelines in the workplace in order to prevent injuries.

You also have to remember that no amount of training can avoid to be involve in accidents. However, these things can be avoided or prevented. Most of the errors may also vary depending on your consistency which usually involves critical details. In addition to that, electrical employees rarely return to their respective task especially if they experienced the arc disaster. They are maimed and affect their lives.

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.
