The IEEE Guide for Performing Arc-Flash Hazard Calculations was updated for the first time since 2002. Read more about how the changes resulted in a new mathematical model and calculation procedure that is more comprehensive, accurate, and complex than before.
To gauge the quality of a study, first, verify that the study will be performed by experienced engineers. Inquire about their education, licenses and experience.
Then ask about their ability to offer a turnkey solution after the study, including offering training, PPE identification, maintenance program guidance as well as products and solutions to help reduce high incident energy.
And finally, ask to see a sample of the final report and compare against the information below.
Don't let the scope of a study scare you.
| 1. | Executive summary |  |
A synopsis of the key findings and recommendations to improve the safety and operation of the power system |
| 2. | One-line diagram |  |
A model of the entire electrical system which forms the basis for the study |
| 3. | Short circuit analysis |  |
Calculates available fault current for each piece of electrical distribution equipment in your facility |
| 4. | Protective device coordination study |  |
Modeling each protective device and its recommended set points |
| 5. | Settings table |  |
A list of recommended settings for circuit breakers and relays |
| 6. | Arc flash incident energy analysis |  |
Used to generate arc flash warning labels showing nominal system voltage and arc flash boundaries, as well as available incident energy and/or PPE category |
| 7. | Input data used in the analysis |  |
A reference to the data upon which the study was based |
