Hi Waross,
You are right, but in this case the impedance is specified to be on the AN mode (from right to left - second column is the project requirement, first column is the manufacturer answer).
I honestly don't understand this answer from the manufacturer. Constructively speaking, if the...
Thank you for the reply, @Gr8blu.
The change in the impedance from 7.5% to 6.6% is really impacting the fault levels downstream. Despite theoretically possible as you explained, when I look at the specification (6.6% @ K=1, 7.5% @ K=8), constructively speaking, I see two different transformers...
Hi everyone,
I have specified a transformer to have 7.5% impedance and k=8. I received a datasheet from the manufacturer with following information:
Transformer impedance - 6.6% @ K=1; 7.5% @ K=8
It is the first time I see a transformer impedance indexed to the k-rating factor. Have some of...
