I am assuming single phase 208 is that correct?
So you do have the upstream results short ciricuit results but the calculations are not valid for a IE calculation at single phase 208v. Zog, I believe this is what PAult is referring to if my assumptions are correct.
No, these are all 480/208V 3-Phase transformers. I was tring to make a generic lablel for all of these since they were all basically the same. Using SKM and having the options set to "Cat 0 if less <= 125KVA" I can find no way to get the IE greater than 1.2 Cal/Cm2 with a clearing time of 2-seconds.
Is it safe to say that all 75KVA 480/208V 3-phase 5.3% xfmrs will be CAT 0 with a EI of 1.2 or less? Or am I missing something?
It appears the SKM ignores the actual data when the <=125KVA option is selected and uses Cat 0 & 1.2 Cal/cm2 on the secondary of all xfmrs <=125KVA.
Is it safe to label these panels with this option selected?
This is all on the secondary on the transformer.
Thanks
