It is important to have a clear understanding about the process of arc flash analysis before beginning the actual work. The following steps are employed to perform an arc flash analysis of a facility.
[7 Steps] — The details of every step go as follows:
1. Data Collection
After setting up the goal of the any sort of analysis (Arc Flash Study in our case), the first and foremost step is to gather information. It is crucial to identify all the required data, the sources of the data and the means of acquiring it.
2. System Modeling
After identifying the ratings and settings of all equipment like panel boards, cables, loads, the power systems engineer then models the system. A graphical layout is drawn on specialized software. That graphical layout is actually the one-line model of the facility.
3. Short Circuit Study
Modeling of the power system on the software is followed by two studies which are the pre-requisites of performing an arc flash analysis of the facility. One of these studies is the short circuit study. As the name suggests, it has to do something when a short circuit occur in the power system.
4. Protective Device Coordination Study
The second study required to perform arc flash analysis is the protective device coordination study. In the wake of a short circuit or any other fault condition, a protective device is used to disrupt the power flow in the faulty feeder. That feeder may be of any panel board, switchboard or even a switchgear.
5. Arc Flash Study
Finally, after carrying out short circuit and coordination studies, the power system engineer has gathered all the required parameters to run the arc flash study on the software.
The power systems engineer then uses the results of Step 5 to determine the minimum working distance, PPE level and requirements at all the electrical points. These may also be determined using the software. Arc flash labels are also generated.
The last step is the implementation step in which the power systems engineer reports the arc flash study results and recommendations to the facility for their on-site application. He submits his findings, results and recommendations in a documented form to the facility owner.
