The analysis of exceedances consists in checking the elements according to the given strength:
 surge – applies to busbars and connectors, exceeding the limit parameters is checked, i.e. peak current i_{p}or surge current i_{p}
 switching – applies to switches, the maximum breaking current I_{cu}is checked for exceeding the symmetrical shortcircuit breaking current of 20 ms calculated for a given element,

Calculation of parameters of asymmetrical shortcircuit current
In the calculation of asymmetrical shortcircuit current, a transformer is modeled depending on the connection arrangement of its windings. The modeled connection arrangements include:
