Workshop Description

This five-day, hands-on professional workshop is designed for experienced ETAP users who want to strengthen their ability to perform arc-flash incident energy studies across a wide range of applications, including energy-sector facilities, industrial and commercial systems, utilities, data centers, battery energy storage systems (BESS), photovoltaic (PV) systems, distributed energy resources (DERs), and other specialized installations. The workshop also includes a two-day advanced course on power system protection and coordination, providing the technical foundation needed for the subsequent three-day arc-flash analysis section.

  • The workshop provides an in-depth discussion of arc-flash physics and examines how effectively calculation models, including IEEE 1584-2018, represent the underlying physical phenomena. Participants will gain practical insight into model application, assumptions, limitations, and engineering considerations. The course also presents the instructor’s perspective on identifying electrode configurations using real-world equipment examples.
  • The workshop emphasizes advanced, practical challenges encountered during arc-flash assessments and demonstrates how various mitigation techniques can be modeled and evaluated. Participants will also explore methods for automated assessment of equipment protection and coordination using ETAP applications.
  • The workshop addresses arc-flash analysis across a broad range of system voltages and technologies, including high-voltage AC systems from approximately 15 kV to 800 kV, medium-voltage systems from 5 kV to 15 kV, low-voltage systems below 1 kV, and DC systems. The examples are structured to help engineers develop the skills needed to perform incident energy analyses across virtually any voltage class. Practical considerations for AC systems operating at frequencies other than 50 or 60 Hz are also discussed.
  • An ETAP workstation is provided for each attendee to support hands-on exercises, demonstrations, and practical study development throughout the workshop.

Who should attend

  • This professional-level workshop is recommended for engineers who have previously completed ETAP training or who are already proficient in the fundamental features and workflows of ETAP.
  • The workshop utilizes the latest ETAP capabilities and emphasizes the current requirements and guidance of applicable IEEE standards and NFPA 70E, with particular focus on how these requirements are implemented in ETAP. Engineers seeking a refresher on the latest arc-flash-related provisions, methodologies, and software features will also benefit from this course.
