I'm not sure if this transistor is two separate transformers

Or it's One transformer

But what kind of transformer has the primary side as a coil and the secondary coil is a Y to do phase angle voltage outputs X,Y,Z phase angle outputs?

 

Are you asking,
-what a phase angle meter is used for?
- how a phase angle meter works?
- how to to use a phase angle meter as a transformer?
- something else

 

no , the schematic I drew , is this two separate transformers? or One transformer?

The Primary is what kind of coil?
The Secondary is what kind of coil?

Is this ONE transformer that has these two kinds of coils in one transformer package?

Yes , it definately is.

The secondary appears to be a Y winding and the primary does not. As drawn, I can't tell if the winding is a helix with anti-clockwise rotations or non-anti clockwise windings. In either case, if the Y windings are, in fact, secondaries, then they must be one transformer because secondaries do not function well without a primary. I am trying to think where I may have come across a transformer with only secondaries and it made me think of a 120 to 12 to 12 to 120 volt isolation transformers where you have the secondaries of two identical transformers connected and the primaries if the second transformer is really the secondary winding but since it is revers, it is really the primary. If the whole thing were encapsulated, you would really have two sets of primaries and no visible (or usable) secondary. But that doesn't help answer your question at all.

In the end I completely agree with you, it is a Y.

What is a transformer called when you have a secondary winding as a Y winding? but the primary is not ?

It depends. Is it for electrical power transformation. is it for sensing or is it for mechanical generation of electricity or, lastly, is it for electrical generation of mechanical power?

 

It has a Knob variac pot

The pot changes the phase shift , phase degree

The primary coil is 26 VAC , the secondary is changing the phase angle

What kind of transformer is this called?

Interesting details but you haven't answered my question above. Your answer will determine what your device is called.

 

Is it for electrical power transformation.

Yes I think so

It just changes 26 VAC in phase into 26 VAC phase degree/shift , depends on the variac dial

is it for sensing

NO

or is it for mechanical generation of electricity or, lastly, is it for electrical generation of mechanical power?

NO

It just changes an 26VAC input in phase voltage into a 26 VAC that can be between 0 degree to 360 degrees inphase or out of phase by the Y transformer coil

 

If that is what it does, there must be some additional coils in the device that are missing from your drawing. Does it work the same way when loads are connected (not just tiny loads).

No it's just those 2 coils

One primary and One secondary coil that is a Y coil , that has 3 outputs , X, Y, Z outputs , this is the phase shift outputs

Does it work the same way when loads are connected (not just tiny loads).

Yes it does work with a load

 

Google up "quad booster", or quadrature booster

 

No that's not it

It's very low voltage 26 VAC, not for Power Electrical transformers

The primary is normal coil
The Secondary is a Y coil , that has 3 outputs , X, Y, Z
Their is a Variac Pot , to adjust the Phase angle of the secondary

 

It looks like a syncro/resolver.
http://en.wikipedia.org/wiki/Synchro

We used then in old fire-control and radar systems for position feedback. I still see them (2 phase resolvers mainly) in direct drive motor control circuits.

How does a synchro transmitter be able to be adjust from zero degrees to 360 degrees?

This is the best source for syncro information.

I'm not supposed to be here, but I will ask anyway.... Does it operate on 400Hz?

 

The word servo comes to my mind. Saw a lot of these in old radars that the AF had back when I was in.

 

nsaspook curious what branch of the service you were in? I worked on automatic tracking radars in the USAF.

USN. IRT to servos I worked on radar (antenna and repeaters), fire-control, RF directional antenna systems and just anything else that needed to be fixed including the old analog DRA system that was a mechanical monster of servo inputs, motors and dials.
