According to the IEEE Std. 1204–1997 system strength definition, the system strength is characterised by two factors; (1) the short-circuit capacity, and (2) the system inertia. In the context of hybrid AC/DC power grids, the system inertia constant is the DC power transferred by the HVDC system and rotor mass of synchronous generators.

Short Circuit Level is the amount of current that flows on the system during a fault. These faults can be caused by a lightning strike, weather conditions or equipment failure. During the fault, the system can see a direct connection to the earth and current flows from all sources into it.
For determining the short-circuit rating for a particular cable, one may ask if should you use the fault level (short-circuit current) at the start or the end of the cable. As per the Australian Standard AS/NZS 3000, the short-circuit current at any point of a circuit shall be interrupted before the temperature of the conductors reaches the permissible limit.
