The voltage, the rated current and the rated frequency are often known or can easily be defined, but how can we calculate the short-circuit power or the short-circuit current at a given point in an installation? Knowing the short-circuit power of the network allows us to choose the various parts of a switchboard which must withstand significant temperature rises and electrodynamic constraints. Knowing the voltage (kV) will allow us to define...
