I have a hi frequency transformer with a secondary of 2200 ohms and a primary of 25 ohms.
Notice the 88 to 1 ratio. I have a power supply that puts out 1232 volts AC and wish to see 14 volts AC output. Notice the 88 to 1 ratio again.
Question: Can I connect the transformers secondary to the power supplies 1232 volts and see 14 volts AC out of the primary?
The question is a learning curve for me.

Transformer impedance changes as the square of the turns ratio. Voltage changes proportionally to the turns ratio. 88:1 impedance is about 9.4:1 turns ratio.

Would that mean 1:1 transformer is always 1:1 ?

Ignoring losses, yes.
Those values are actually the transformer specs, not what you measured with a multimeter, correct? If so, then all is good. Also, if its a HF transformer, make sure you use it only at HF.

Do you have a problem with molten enamel?
