High-Voltage Arc Flash for Overhead Conductor Systems

Arc flash analysis extends well beyond the scope of IEEE 1584 and NFPA 70E methodology for transmission, distribution and renewable energy systems. For many years, the industry has been lacking an “all-in-one” solution for performing arc flash analysis on DC, LV, MV and HV AC systems. ETAP ArcFault™ provides a validated method for performing arc fault simulations in T&D open-air overhead conductor systems plus it provides two methods to determine the incident energy for arc-flash in 3-phase enclosed equipment for 15 to 38 kV renewable energy collector systems. This presentation explains the background and methods for arc fault simulations and explains how ETAP ArcFault helps utilities comply with OSHA requirements to perform arc-flash analysis for systems voltage above 1.0 kV.

Create fully customizable Arc Flash Hazard Labels in any language for any standard with ETAP eLabelMaker™

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.

Generator Brush Collector Ring’s Arc Flash Hazard, A Safety Concern!

For some types of generator exciter systems, collector rings and brushes are used to provide energy from the exciter to the rotating field. The brushes wear down and constantly need to be replaced with the unit on-line and while brush/ring assembly is still energized, a risky and unsafe maintenance operation and may cause a serious harm. A potential shock and arc-flash hazard. This presentation addresses the important and dangerous maintenance of worn-down collector rings and brushes, electrical safety, lack of standards and guidelines, and a first possible calculation method.

AC and DC Arc Flash Methods for Renewable Energy Systems

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.

Industrial Plant Electrical Risk Management Program

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.

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.
