ANSI Fault Analysis

A_FAULT provides short-circuit calculations in full compliance with the ANSI C37 standards.

 

It offers separate solutions for low, medium and high voltage systems and for symmetrical, momentary and interrupting calculations as defined in the standards.

For medium and high voltage systems, the momentary and interrupting values may be calculated using either the E/X or E/Z methods permitted by the standards. Both AC and DC decrement curves required by the total current rated standard (C37.5) and the symmetrical rated standard (C37.010) are used by the program.

 A_FAULT Study Module

 

Benefits:

bullet

Design safer power systems by calculating equipment ratings per ANSI standards.
bullet

Save time by automatically applying ANSI C37 and IEEE 141 multiplying factors to generators and motors.

bullet

Increase efficiency with custom data reporting featuring X/R, E/X or E/Z methods and values for the application of low, medium, and high voltage breakers.
bullet

Communicate effectively with quality reports.

 

Features:

bullet Reports three-phase, phase-earth, phase-phase, and phase-phase-earth fault values.
bullet Reports values for both total current and symmetrical rated breakers.
