Short Circuit Studies:
Even the best designed power systems experience short circuits, resulting in extremely high levels of current. Protective devices such as fuses and circuit breakers are required to quickly and safely isolate the short circuit with minimal damage to equipment and minimal disruption of operations. Additionally, cables, buses and switches must withstand the mechanical and thermal stresses associates with the high level of current. A short study completed by inoLECT compares the system’s available fault current with the momentary and interrupting ratings of equipment. All underrated equipment is identified and recommendations are made to provide a safe interruption of short circuits.
