Transformer half crest time

  1. Mar 21, 2015 #1
    during reading power transformer (0.71/33) kv data sheet, I found term "half crest time" which equals to 0.8 s,
    the question is: what is that time and why is important?
    thanks and kind regards.

    It has to do with inrush current. I googled the phrase and found 8 references that can give you more detail.
