The amazing and mysterious ESP switchboard

The amazing and mysterious ESP switchboard

The amazing and mysterious ESP switchboard

(OP)
Greetings!

A gentleman from the company I am doing some consulting for said that there is a switchboard for ESP systems that does not require the use of transformers to step down voltages.

For instance, he says that this box can take 4160V from primary field power, and spit out 2400V to the pump/motor, without using any transformers.

I always thought that whenever you stepped down voltage, it HAD to use a transformer of some kind.  Am I right?

It could be he's thinking of a variable speed drive, but for our application, there's no way a VSD could cut the voltage in half just by adjusting the frequency.  At least I don't think.

So have any of you heard of such a switchboard?  I've talked with Schlumberger, Baker Hughes, and a few others, and they all say that they've never heard of such a thing.

One guy did say that there is a switchboard made by someone called a "FAC" something or other, but it is just a transformer box with a controller on the front of it. So it still uses transformers, they're just packaged as a single unit.  He also said he's only seen them used over seas!

If anyone has any insight to this issue, please contact me!

RE: The amazing and mysterious ESP switchboard

You might post the question on one of the electrical fora.  I know there are magic boxes now that take in single phase 120V and give you 3-phase 440V (I think, I know it is 3-phase, but I'm not certain of the voltage) without the effeciency hit you get with an add-a-phase.
