13K SINGLE TRANFORMERS TO 480/277 VOLTS 1200 AMP. size TRANSFORMERS ?

Re: SIZE TRAMSFORMERS

Voltage * current * sqrt (3) = size.

The voltage is line to line. Currrent and voltage should both be RMS, both from the same side of the transformer (use 480V and 1200A).

Then add any extra spare capacity that might be prudent.

Re: SIZE TRAMSFORMERS

If you want to use single phase transformers use three 333KVA single phase transformers configured delta-wye. 13.800 KV primary delta and 480/277 secondary. These three will give you 1200 amps on the secondary.

I think he meant,

"Happy Holidays to all.

He missed the period.
