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.
Fault current plots for a short circuit study.

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.
