IEC61363 Study Module

The IEC_61363 Short Circuit Study calculates the three-phase short-circuit duties in an unmeshed electrical power system operating at 50Hz or 60Hz. It represents conditions that may affect typical marine or offshore installations more significantly than land-based systems, including more emphasis on generator and motor decay.

The primary reasons for performing IEC61363 short-circuit calculations include:

1. Obtain the short-circuit current magnitude at each point in the power system;
2. Compare the calculated fault current to the ratings of installed equipment to verify that the equipment ratings are adequate to handle the short circuit current;
3. Support proper selection of circuit protection equipment for protection and coordination.
