Equipment data for short circuit calculations

Determining available short circuit fault currents is one of the most important aspects of designing power distribution systems. Short circuits and their effects must be considered in selecting electrical equipment, circuit protection devices, and carrying out arc flash analysis. Short Circuit Analytic short circuit calculation software is offered in effort to satisfy the need for a convenient, comprehensive method of calculating fault currents. The SCA V1.0 software allows to quickly and easily obtain accurate potential short circuit currents at each bus in a power distribution system.

This program, other programs, or hand calculations can be used to perform short circuit calculations. Any method used required specific data on the power distribution system components. Next follows detailed description of the data required by the SCA V1.0 software on its input for each type of circuit component, and how to obtain the data.
