Arc Flash Hazard Analysis / Risk Assessment
1. What are the steps involved in Arc Flash Analysis? A. Arc Flash Hazard Analysis or Risk Assessment is a study conducted by trained safety experts to analyze electric equipment and power systems in order to predict the amount of incident energy from an arc flash. According to IEEE std 1584, there are 9 steps involved in this Arc Flash Analysis, which we are going to discuss here. Step 1: Collect the system’s installation data: The largest effort in an arc-flash hazard study is collecting the data from the site. Start by reviewing the one-line diagrams and electric equipment, site, and layout arrangement with people who are familiar with the site. The diagrams have to be updated to show the current system configuration and orientation before the arc-flash study starts. The one-line diagrams must have all alternate feeds. If SLDs are not ready, prepare them. Once the diagrams are completed in the basic electric system scheme, enter the data needed for the short
