transformer 380 volts prim, 208/120 volts sec, 3 phase, 30 kva?

Answer 1

Curious question. The secondary 208/120 3 phase voltage is indicative of a grounded wye 3 phase. This indicates the necessity of primary electric supply of 3 phase. The primary terminals require a voltage of 380 volts per phase. This will determine whether or not the primary terminals are connected phase to phase or phase to ground. The 30KVA is 30 KiloVoltAmps. This is a measure of the apparent power available for consumption. In practice though, one could almost use KW interchangeably. The primary voltage of 380V is unusual. Could you have meant 480V?

Answer 2

Take a volt meter and verify from each prong to a pair metallic area on the hollow. if you're in the U. S., there'll be 2 warm wires each 120v to impartial/floor and 240v to at least one yet another. you want an electrician to do the conversion besides. A 240v outlet like that oftentimes does no longer carry a impartial wire, in person-friendly words a floor. it isn't criminal or risk-free to apply the floor for impartial. someone qualified needs to tug a impartial wire and redo the hollow so that you've 120v. If the hollow has 4 slots then there should be a impartial wire and also you gained't opt to tug one. No transformer is critical nor do you should use any.

Answer 3

What is the question? And, is the 380 volts leg-to-leg, or leg-to-neutral? The price of such a transformer would probably be around US$2,000. Don't drop it on your toes.

Answer 4

It is a very peculiar transformer.
