HV Arc Flash Studies for one of the Largest Utilities in South America

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.

AC Arc Flash using IEEE 1584 - University Campus Case Study

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.

Data Center Power System Expansion: DC Arc Flash Case Study

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.
