Answer Question
Short circuit tests accordig to the standard (IEC 60909-4)
Good morning,
I have a problem with modelling 1 phase and 3 phase short-circuits in this circuit: https://ctrlv.cz/shots/2018/01/29/2qIB.png.
Here you can see the defined parameters: https://ctrlv.cz/shots/2018/01/29/gHaB.png.
Could anyone help me, please? I tried to make a simulation like this: https://ctrlv.cz/shots/2018/01/29/WKX..., but I couldn't get a results, which are counted in the Standard (IEC 60909-4). Because I don't really know, how to make a proper model of a network feeder and two-winding transformers - I mean, how to define their inner impedances and positive and zero sequence impedance. If anyone could help me, I would be very thankful, because I need results until friday. Thank you very much.
