Short Circuit Currents According to IEC 60909

[@LuisCunha-uq8pn]

Hi! @24:12, why do you need an interlock between the sources if you say that both transformers will feed in parallel? The mechanical interlock is to prevent the two circuit breakers from being closed, i.e. only one of the transformers can supply the bus.

Very Informative. Thank you for this.

From where I can find table shown in last of video for seeing short circuit levels on different lengths and sizes of cables ?

Thank you

why do you neglect the c factor in your numerical example?
