IEC 60909 and ANSI standards comparison with ASCC based fault calculations of Iraqi power system

The calculation of short circuit (SC) current has to be accurate because of their importance in power protection system’s design and to determine the capacity of the protective devices. Therefore, there are many standards and programs to estimate SC calculation. The aim of this paper is to provide f...
