ETAP Arc Flash Auto-Evaluation allows you to quickly evaluate arc flash incident energy with automated protective device coordination study to significantly reduce costly modifications and mitigation equipment. Learn more
This webinar presents the European/German standard DGUV-I 203-077 for arc flash hazard calculations. This method, just like IEEE 1584-2018, is in use in many European countries. We will compare the German Arc Flash methodology to IEEE 1584-2018 and introduce ETAP tools available for Arc Flash calculations based on this standard. Application examples as well as features & capabilities will be presented. Learn more

In this video, we demonstrate how to use ETAP’s Lightning Risk Assessment (LRA) module to assess the risk of a lightning strike and the probability of damage. Learn about the LRA calculation methods used in ETAP and how to perform the LRA to comply with internationals standards NFPA 780-2020, 2014 and IEC 62305-2: 2010. Explore the important reasons behind Lightning Risk Assessment. From lightning as the number one cause of power surges, to preventing damage, fires and other harm to lives and property, accounting for unpredictable weather patterns and asset protection, as in buildings, power infrastructure, and human lives, ETAP's Lightning Risk Assessment module will calculate the risk and suggest steps to prevent harm to humans and infrastructure.
This presentation focuses on HV arc flash hazard analysis, as part of a multi-voltage AF study (115, 34.5, 13.8, and 0.22 kV) for one of the three largest utilities in South America with hydro and renewables generation and T&D. It demonstrates the versatility of the ETAP ArcFault™ to assist in the calculations and estimates of electric arc currents and incident energy level for HV substation equipment. The presentation discusses how ArcFault study results were used to select engineering and administrative control strategies, personal protective equipment (PPE), changes in protection schemes and adjustments to reduce electrical risks in operation & maintenance of electrical T&D systems.
Since the release of IEEE 1584-2018, the industry has been challenged to reach a consensus on applying the new standard. The most significant application “pain” so far has been identifying actual equipment data for input to the study, including bus gap and electrode configurations in the equipment. A case study of an arc flash analysis for a large university campus with MV and LV power distribution equipment of different types, vintages, and manufacturers is presented. The presentation highlights selection of electrode configuration(s) for various equipment types and voltage levels and correct application of arc current and enclosure size correction factors to significantly reduce the data entry time and effort. The presentation will cover upcoming IEEE P1584.1 revisions to apply IEEE 1584 for arc-flash hazard calculations directly from the revision subgroup chair.
Case study of a a power system study, which involved the replacement of an extensive UPS system at a data center. The studies included short-circuit, protective device coordination, and arc-flash hazard analysis for both the AC and DC systems consistent with the NFPA 70E 2018 and IEEE 1584 2018 Standards. The DC equipment as installed required mitigation efforts due to high incident energies. This presentation details the analysis, findings, and recommended mitigation for anyone embarking on similar retrofit or expansion studies.
