Check short-circuit withstand
Will the transformer withstand the fault current of your installation? Converts the rated short-time current to your clearing time.
Input values
Result
- Permissible current for this duration
- 60 kA
- Rated dynamic current Idyn (peak)
- 150 kA
The transformer withstands this short-circuit current.
Heating follows I²·t, therefore I(t) = Ith · √(1 s / t). To IEC 61869-2, Idyn is 2.5 times Ith.
