The Significance Of Arc Flash Analysis

By Dorthy Lloyd


You might be thinking, yes it is true that arc flash is quite dangerous and even cause death to all workers. Most people in the industry are not aware of this danger. People also heard that explosions are hotter than the typical heat of the sun. According to studies, electric arc is considered as hottest thing on Earth in addition to laser.

That is why, people are warned with the effects of the blast. Everyone knows that arc flash is very hot. Thus, employees must wear protective gear and consider the warning labels. In order to prevent any disaster, it is important to do arc flash analysis. Employees are required to undergo training, proper supervision and a positive attitude towards the regular practices and guidelines in the workplace to prevent injury.

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.

There are many electrical risks including shock, electrocution, flash and blast. Most often, electrical risks happen when materials are insulated and don't contain applied voltages. Short circuits or insulation may only create a certain bypass in the circuit. Heat will be generated through current flows and could be vaporized the materials which create arcs.

Since the demand for electric increases, most transformers at industrial and utility level are also upgraded and replaced with those having lower impedance and higher ratings. Mostly, transformers are operated in a parallel level for the satisfaction of requirements for the reliability of the system. Most of those modifications may also cause an increase in fault current and may result in electrical energy.

Most of the employees also know and understand the shock risk but only some understand the hazards. That is why, analysis is necessary. There are companies that hire qualified engineers to keep the system up to date. But, because budget is reduced and companies experience downsizing, such function may also vanish on time.

Risks may actually happen when someone has no ideas on the job and when people are working in the equipment without any experience and skills. One of the risky situations you may consider is when a worker is working near the device or equipment. This is because the doors can be opened and may result to risks.

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.
