Short Circuit Analytic

Short Circuit Analytic version 1.0 for iOS (iSCA V1.0) software performs available short circuit fault current calculations in three-phase electric power systems you are working with. The program takes into consideration electrical parameters of the power supply as well as the power distribution system including utility, cables, transformers and motors. The short circuit software automatically converts the entire system into a unique impedance unit from which the short circuit current at each and every point is calculated.

The source can be set as a transformer supply or a busbar with a specified short circuit level. If a transformer source is used, the short circuit level on the primary side can be set to infinity by setting the data field blank.

Add components one by one to build up a single line diagram. The components can be cables, transformers and a motor. After a component has been added, its data can be edited by clicking on the component when displayed on the screen.

Click on 'Calculate' to estimate the short circuit currents at each busbar. The calculations are approximate and factor in short circuit current contributions from the source and maximum of one motor only.
