ABSTRACT Disturbances in the electrical distribution system can be caused by several factors, one of which is caused by a short circuit current. The short circuit current in this electrical distribution system occurs for a short time and causes the nominal voltage to drop temporarily which is called a voltage sag. Short circuit faults that occur in the electrical distribution system are sh…
