Load of three two-phases resistances
Load of three two-phases resistances
(OP)
Hi to all.
I have a question that maybe simple for some of you guys.
I have to supply a transformer with a cable (primary) sized for three loads (secondary) of 150KVA two-phases resistances @ 400Vac phase-to-phase.
What will be the resulting, effective load on the Primary, as to size the primary cable? From my prespective, as i will load the phases with balanced two-wires phase-to-phase load, it should be approx 2/3th of the resulting 450KVA, but I am unsure, as it's not usual for me to supply two-phases loads.
Thanks for your replies.

I didn't found the Omaha part of it (only "sweet fudge"...), but the "fudge factor" is well known.
I will go for the 450KVA, then.
Best regards.
