Workshop Description

  • This 5-day professional hands-on workshop is designed for experienced ETAP users looking to take advantage of the full capabilities of ETAP software for performing arc-flash incident energy analyses and to simulate advanced I.E. mitigation techniques.
  • This workshop provides a full discussion on the new IEEE 1584-2018 arc-flash model. It includes background and insights into the model development and validation, as it is essential to understand how the new model combines empirical and arc-flash physical behavior. An analytical opinion on how an arc-flash incident energy study changes when applying the new electrode configurations is provided and features of the new arc-flash model are discussed.
  • This workshop focuses on solving the advanced practical problems related to arc-flash assessment and mitigation techniques, utilizing the new methods of automated evaluation of equipment protection & coordination in ETAP applications.
  • This workshop covers all aspects of arc-flash analysis from HV, MV, LV AC arc-flash to DC arc-flash applications and models. The examples are designed to enable an engineer to effectively perform incident energy analysis for any voltage level. Some practical discussions on how to handle AC systems with frequencies other than 50/60 Hz are included.
  • An ETAP workstation is provided for each attendee.

Who should attend

  • ETAP professional workshops are recommended for engineers who have taken prior ETAP workshops and/or are proficient in basic functionalities of ETAP.
  • This series of workshops are to apply latest ETAP in more practical cases and how to fully utilize ETAP capabilities most efficiently to analyze the dynamic behavior of the systems.  
  • Recommended for users who have practical experience with the details of power system modeling, managing 3-dimensional database and utilizing device libraries in the ETAP application.
