= Short circuit ratio (electrical grid)
{wiki=Short_circuit_ratio_(electrical_grid)}
The short circuit ratio (SCR) is a dimensionless parameter used in the context of electrical grids, particularly in the analysis of power systems and in studies related to stability, fault analysis, and the performance of power-generating units, especially synchronous generators. It is defined as the ratio of the system strength to the rating of the generator or power source.
