Short-circuit power and short-circuit resistance

Short-circuit power is the theoretical current that will run in the event of a short circuit if the protection has not yet intervened. This theoretical short-circuit current at the point of the voltage junction depends on the impedance of the voltage source (power-supply transformer, generator, etc.).

The short-circuit power can be calculated, but this can be difficult because not all data on the electrical installation is available in many cases. The standard value lies between 6 kA and 60 kA. However, as much as 150 kA must be taken into account for a voltage junction in a substation close to the power-supply transformer.
