In Need Of 3 Phase Step Down Transformer
 

We are looking for a 3 Phase Step Down Transformer. We have a 3 Phase 100kw generator and need the step down transformer to bring the power down to single phase for use in a church camp facility.

If anyone knows of any good deals out there please let me know. (preferably in the Texas area... I don't know how big or heavy these things are and how hard they would be to ship)

Thanks,...

Veeerrrrrryyyy Heeeeaaaaaaavvvvvyyy for thier size!
We had one for our Church in Burnaby for a AC Unit that we bought.
They tend to be noisy too!

I pray you locate one local at a good price!

OH BOY! an electrical issue!

A couple of things:
Austin International

nice folks --easy to deal with, tell them what you want
primary side 480V primary (delta or wye) to 208/120 (wye) secondary.
primary will have either 3 wire connection or 4 (nuetral) but secondary MUST BE 4 wire.
You will be looking for a transformer rating that is at least your generator rating x 1.25 (if generator is in Kw), this is because you will want to match the KVA capability of the transformer with the KVA capability of the GENERATOR.

A slightly larger xfmr will not hurt you at all.
A dry type transformer WILL GET HOT and must be under a shed as a minimum. In the smaller KVA sizes (200 and below) most transformers will be dry type.

This is a VERY COMMON size transformer (480V (3wire) to 208/120V (4 wire secondary), since almost every commerical building has the need for the same thing.

REMEMBER!!!! GENERATORS ARE LIMITED BY THEIR HIGHEST PHASE LOADING...in otherwords...their rating is SET by the SUM of three things (PHASES) being utilized, THE TOTAL CAPACITY is only there when each of the three phases are fully utilized.

SO TELL YOUR CAMPING BUDDIES....be very careful in how they load the branch circuits on the distribution panel that will be on the secondary of the transformer

----IS THIS FUN or WHAT!!!! I haven't enjoyed myself this much on AFF since talking with Adino about water baptism's equivalence in destroying a taskmaster with the Red Sea's destruction of a former taskmaster!

Example:
Your Generator is 60KW 3p, 4w with a 480V output.
Make sure your transformer is at least 75 KVA and has a secondary that is
4 wire 208/120 (once you have the 'double' secondary voltage you have a four wire connection because it is the LINE to NUETRAL voltages that provide the 120V.
