Short Circuit Software

Save hours of tedious hand calculations and take the guesswork out of short circuit studies by automating the
process with multiple calculation and result analysis short circuit software tools within ETAP.


ETAP short circuit analysis software analyzes the effect of 3-phase, 1-phase, line-to-ground, line-to-line, and
line-to-line-to-ground fault currents on electrical power systems. The fault current calculation software simulates
the total short circuit currents as well as the fault current contributions of individual motors, generators, and utility
ties in the power system. Fault current short circuit duties are in compliance with the latest editions of the ANSI/IEEE
Standards (C37 series) and IEC Standards (IEC 60909 and others).


The 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 with the purpose of finding
the worst-case fault current device duty. Built-in intelligence allows the short circuit analysis software to automatically
apply all ANSI / IEEE or IEC factors and ratios required for high- and low-voltage fault current device duty evaluation.

Instant Results, Comprehensive, Graphical Summary
 

Short circuit software determines fault currents and automatically compares these values against manufacturer short circuit current ratings. Overstressed device alarms are automatically displayed on the one-line diagram and included in short circuit study reports. ETAP closely monitors industry standards and OEM data to ensure the Short Circuit study module is always up-to-date. The Short Circuit study module seamlessly integrates with device coordination and performs arc flash hazard calculations.
