Short Circuit Analysis

Instant Results, Comprehensive, Graphical Summary

Perform Device Duty Calculations using ETAP's short circuit analysis software which allows you to determine fault currents and automatically compare these values against manufacturer short circuit current ratings. Overstressed device alarms are displayed on the one-line diagram and included in short circuit  analyzer and study reports.

ANSI Duty Cover

Analyze the effect of balanced and unbalanced faults using ETAP short circuit analysis software:

  • 3-phase or 1-phase
  • Line-Ground
  • Line-Line
  • Line-Line-Ground

ETAP short circuit software makes it easy to go from selecting elements, (from the comprehensive library of short circuit current ratings), to performing dozens of different types of short circuit analysis. Analyzers, plots and reports allow for quick determination of the worst-case fault current device duty.

Learn how EEEngineering uses ETAP to transform power studies into engaging, interactive presentations

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.

ABB FCL Application Engineering for IS-Limiters

ABB FCL Application Engineering for IS-Limiters

This presentation will feature covert ABB Fault Current Limiter (FCL) application engineering for Is-limiters. We will explain the fault current limiter technology by using the well-known ABB FCL Is-limiter. The FCL technology will be introduced, how it clears a short-circuit fault current compared to a standard circuit breaker, and the major components of an FCL. The theory of the application engineering process and the calculation of the tripping value for an FCL will be introduced. Based on an actual customer project, it will be shown how ETAP has facilitated the complex FCL application engineering, and examples will be provided of how the real tripping value for a fault current limiter is determined. The session will conclude with an overview of how etap can already be used today for an FCL application engineering and what will be enhanced in the future.
