Based on power quality study which was performed there is a
current THD level of average 7.8% .
Transformer is 500KVA.
I am trying to figure out what would be the derating factor for this transformer.
I have all RMS values for 1-16th harmonics and based on that I am getting k=1.3 which is pretty low!!!
I can not use IEEE 57.110-1986 because I don't have any test data or detail info on transformer.
I know that there is a curve for transformer capacity based on k factor rating,however I belive that is based on loss calculations and...
Any suggestions on this.
Is there any other way of caluclating this
Thanks for all the feedbacks.
