Short Circuit Current and Time Current Coordination Studies

Accurate short circuit and coordination studies are essential for electrical safety and reliability. Using SKM Power Tools, we model electrical distribution systems and establish a protection scheme that responds correctly during faults.

Our studies provide:

• Calculation of available short circuit current at each point in the distribution system

• Comparison of available fault levels to the interrupting ratings of existing and proposed equipment

• Development of time current coordination curves to minimize the extent of outages during faults

• Recommended settings for breakers, relays, and protective devices that support selective coordination and safety

These studies reduce the risk of equipment damage, limit arc flash exposure, and prevent nuisance tripping and unnecessary facility wide outages.
