Hello Deep, As an example you could check the "Planning Manual - Planning with SIVACON S8, Flexible Low-Voltage Switchboard", available on http://support.automation.siemens.com/WW/view/en/20356391/133300. Chapter 8.10 provides a table showing short-circuit currents of three-phase distribution transformers.These are maximum values on the transformer output. The longer the cable way from the transformer to your panel the lower this value (impedance of the cable). Regards, Sentronix |

Good Day, On how to determine the interrupting capacity of the breaker you should cumpute the Isc your network...there is a lot of computation needed to know in interrupting capacity(KAIC). here is the attached file hope that can help you...if you have question and feedback im open to help....

Hi, In Siemens, we recommend to use the best way of calculating Fault level and that is SIMARIS Software... please refer the below link and download it freely and use extensively... https://www.automation.siemens.com/mcms/electrical-design-software/en/service-support/simaris-software/Pages/default.aspx |

Hi There Can any tell me how the Fault level for transformer is decided as from that fault level the PCC & MCC panel are designed ???
