Asym L-L, Sym L-L, L-G Fault Data (?)
Asym L-L, Sym L-L, L-G Fault Data (?)
(OP)
Greetings,
I have received available fault current data from the utility in the form of L-L instead of Three phase. I have not seen this before from my local utility. I am wondering if this is a mis-speak because I was given this data third hand.
I have not been successful reaching the utilty planner to clarify so I was wondering if there are any thoughts out there....
Given the L-L sym and asym and the L-G fault current, is it possible to calculate the three phase?

If not, I'd ask for clarification.

You still need clarification. Most likely, you have a 3Ø fault value, not a L-L value. If it is L-L, is it L-L or double Line-to-Ground? Without knowing what you have, it's no use calculating anything.
