Short-circuit current represents the anticipated current flow within equipment when faults occur.
It is crucial to properly size protective devices, such as breakers, based on this current to ensure they can interrupt fault currents.
Designing protective systems that can rapidly isolate faults is essential for preventing damage and maintaining the stability of the electrical grid. Short-circuit current is crucial to understanding how the utility evaluates the size of protective equipment used for new interconnections.
POIs with expected high short-circuit current will require protective equipment specifically designed to interrupt those high currents.
This will directly impact your project’s interconnection cost.
The short-circuit current can be found on our platform within the Point of Interconnection (POI) details.
