The more data you can obtain for the study, the less assumptions you will need to make.Īn arc flash study with lots of assumptions about the site can lead to incorrectly calculating the incident energy values. Chapter 2: Data Collectionĭata collection is without a doubt the most important part of performing an arc flash study. The goal is to collect as much information about the site as possible and reduce the amount of assumptions you make so your calculations are better.Īrc flash studies with very few assumptions are worth their weight in gold in this industry. The fundamental phases are data collection, followed by short circuit analysis, and then arc flash study. Performing an arc flash study is typically done in phases or layers. Having an arc flash study done is not the law, but identifying your known hazards and letting people know about them definitely is.Īrc flash studies just so happen to be the best way to do that.Īt the end of the day, if you are an employer who puts worker safety on a back burner, you will be held liable if an accident happens! Performing an Arc Flash Study It is employers’ legal obligation to ensure employees adhere to existing regulatory requirements. Without this information and proper training, your electricians are left in the dark and will have little idea of what PPE to use when servicing the equipment. Why Arc Flash Studies are Important? Worker SafetyĪn arc flash incident energy analysis (or simply, an arc flash study) is first and foremost an engineering investigation designed to provide detailed safety information about a piece of equipment or circuit part to qualified workers servicing that equipment.
Lastly, I want to emphasize that I plan on keeping this guide updated regularly, so please check back often for new information. If you want to read up on the theory behind the ETAP calculations, I encourage you to do so using their help directory.
