In most cases, SCCAF (Short Circuit Coordination Arc Flash) studies are done by engineering firms, which then submit reports to facility owners. The challenge is that those reports tend to be lengthy (up to 5,000 pages), not engaging, and hard to grasp for facility personnel. ETAP's powerful graphical and presentation tools can help make those reports livelier, informative, and more engaging. This case study will discuss how you can summarize lengthy power studies reports within just a 30-minute interactive meeting, and highlight how the final ETAP model can be used, with its powerful graphical interface and presentation tools, including Data Blocks, Multiple Presentation layers, Sequence of Operations, and Arc flash calculator.

Engineers face unique challenges when calculating DC Arc Flash (DCAF) incident energy for Battery Energy Storage Systems (BESS). Battery short circuit current is highly variant, and factors such as battery chemistry and the installation arrangement of BESS contribute to significant differences in short circuit behavior. As well, traditional methods of calculating DCAF may not be sufficient when it comes to BESS. Nexamp Energy studied these variations, including considerations for personal protection equipment (PPE). The Transient DC Arc Flash solution provided by ETAP was also examined to highlight the usefulness of model validation and the importance of high quality analysis methods for providing better accuracy in DCAF analysis for BESS.

Multiple arc flash incident energy mitigation methods are available, but how does an engineer know which is best for their client? This presentation identifies an approach to follow to pick the method, considering effectiveness, practicality, feasibility, and overall best option for realistic study results. With extensive experience with arc flash studies for many clients of all sizes, Mangan provides a real world demonstration of a project for a refinery client. The interplay between motor starting and arc flash analysis was evaluated, and mitigation recommendations were customized for the system. The challenges encountered during mitigation are identified, and the proposed solution is analyzed using ETAP Load Flow, Short Circuit, Arc Flash and Motor Acceleration Analysis. Safe motor operation, safe motor starting and arc flash protection are provided through customized mitigation methods and thoughtful system design.

ETAP Arc Flash Analysis software includes a variety of arc flash hazard safety labels in multiple languages. This webinar will demonstrate the new eLabelMaker™ features, such as two-incident energy result labels, QR codes, and fully customizable label. Create arc flash labels in any language even without having access to specific ETAP Language Editions. Existing arc flash labels are still available with every release, but in addition, the eLabelMaker™ allows the user to create any type of label, depending on the specific needs or regional standard requirements.

This presentation will address the difficulties and lessons learnt on performing arc flash analysis using available methods (outside the voltage limits of IEEE 1584-2018 standard) on a 2.3 MW PV generation facility. The analysis includes system modeling, short-circuit, arc flash (both AC and DC) using various applicable calculation methods that best fit this application along with available tools in ETAP and generating worst-case arc flash deliverables.

The Electrical Risk Management (ERM) group at FTI uses ETAP to provide short circuit, coordination, and arc flash studies as a part of building a safety program for industrial facilities around the US and Canada. This presentation will describe our approach to an overall safety program and the ways that a safety program encompasses more that just an engineering study. Some topics to be discussed are the need for maintenance personnel to understand the labeling, assessing the risk vs. just looking at the label, the choice between full coordination and arc flash hazard, field verification, and bolted fault current vs arcing fault current as it relates to equipment evaluation. We will look at the ETAP model of one of our industrial customers and discuss the benefits of using ETAP for our studies – reliability, adaptability to many systems by using configurations and scenarios, wizards, availability of DC and MV calculations, Star TCCs, ease of exporting reports to Excel, and solar and wind sources capability.

Learn about ETAP ArcSafety, an all-in-one AC & DC arc flash solution for LV, MV & HV systems that improves safety, reduces risk, minimizes equipment damage, and validates mitigation techniques.

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 2027 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.

The topics discussed in this video are the characteristics of an Arc, DC Short Circuit calculations, the Maximum Power Method, the Stokes and Oppenlander Method, Paukert Method, how these methods are utilized in ETAP, the calculation of incident energy, how to configure ETAP 11.1 to determine whether or not you are dealing with an open or closed air equipment, and the result analyzer.
