Short Circuit Software Device Duty Calculation & Evaluation for Single-Phase, Multi-Phase, Panel, & UPS Systems

ANSI and IEC standards are used for calculating short circuit current for parts of the network below main panels, subpanels, UPS, and phase adapters. Device duty calculation compares the calculated fault current from these networks for evaluation of protective devices and automatically generates critical and marginal alerts based on user-defined alarm limits.

The fault current simulation program considers the upstream contributions (from the 3-phase system) towards the faulted elements in the 1-phase subsystem by considering the impedance networks of the 3-phase system (i.e. positive, negative and zero sequence).
