how do you connect a dry type transformer to a 250v wye system to get 120v.the primary has h1-4 and the secondary x1-4.?
Dry type Transformers should work fine with a primary H1-4 and X1-4. If it's not working check to make sure that you're really getting 250V.

What are the two coils in a transformer?
primary and secondary coilsAnswerPrimary and secondary windings.
What happen if the number of loops in the primary and secondary coils in a transformer are the same?
If the number of turns in the primary is the same as the secondary, this would be an isolation transformer. Primary and secondary voltages should match (minus the inherent transformer losses), as should the current.
Is possible to put 3 phase transformer primary as secondary and secondary as primary?
A: The only way can be possible if the transformer is an isolation type. Yes, you can put the input into the secondary side. This will create a step-up transformer.
What is the function of the primary current when the secondary winding of the transformer is open?
When the secondary of a transformer is opened, there is no longer any load on the transformer. There will be some current flowing in the primary winding, which is needed to induce the voltage in the secondary. This primary current is referred to as the "no load" current, and is indicative of the core losses in the transformer.
Is the transformer's iron core called the primary?
No. the primary winding is called the primary; the secondary winding is called the secondary. These are both wrapped around the iron core of the transformer. The core helps magnetically link the primary and secondary, which causes the transformation of voltage and current from primary to secondary.
Why you uluminium on primary side of transformer?
This isn't the case. You can have aluminium or copper on primary or secondary side of a transformer.
If a Transformer primary and secondary are equal?
You will have a 1:1 ratio isolation transformer.
What is difference betweena step up transformer and step down transformer?
The difference between the two transformers is the coil ratios between the primary and secondary windings. A transformer that increases voltage from primary to secondary has more secondary winding turns than primary winding turns and is called a step-up transformer. Conversely, a transformer with fewer secondary windings does just the opposite and is called a step-down transformer.
A transformer with a primary of 1200 turns and a secondary of 400 turns has what ratio?
A transformer primary of 1200 turns with a secondary of 400 turns is a ratio of 3 to 1.
How to differentiate 110v or 220 transformers?
The way to identify any transformer is to look at the the transformers nameplate. The primary side will be designated H1 to H4. This is the primary side and the voltage will be stated as to the voltage to connect to. The secondary side will be designated X1 to X4. This is the secondary side and the voltage will be stated as to the voltage it will be transformer to.
Does the primary winding VA equal the secondary winding VA when a transformer is loaded?
No, the primary winding VA does not necessarily equal the secondary winding VA when a transformer is loaded. The power output on the secondary side may differ from the power input on the primary side due to losses such as resistive and core losses in the transformer. The transformer's efficiency will determine how close the VA on the primary winding is to the VA on the secondary winding.
If a transformer has 20 primary windings and 100 secondary windings and the secondary voltage is 25 what is the primary voltage?
Transformer step-up/step-down voltage is turns-ratio, so if a transformer has 20 primary windings and 100 secondary windings (a turns-ratio of 1 to 5) and the secondary voltage is 25, then is the primary voltage is 5.
