Transformer with the same primary & secondary voltage
Transformer with the same primary & secondary voltage
(OP)
Does this type of transformer exist? Primary and Secondary voltages are both the same, 600V, but it's Delta to Wye connected, 3-phase, ~400KVA.
The reason for asking is, I want to take advantage of the taps in a transformer to give a small boost to voltage that is too low. Can this be achieved another way?

RE: Transformer with the same primary & secondary voltage
If you just want a small increase in voltage, it is more economical to use a boost autotransformer. Look in Eaton or GE catalog for "buck/boost" transformers. For 400 kVA of load, if you want to boost the voltage by 10%, you would need roughly a 40 kVA autotransformer.

1. To reduce the fault current on the other side transformers. Say if you are wiring to distribution boards for light fixtures etc.
2. Your question. To correct the voltage if required.

Are there auto tap changers in a transformer? Are they reliable?
What about a voltage regulator?

If they're well made, tapchangers are generally extremely reliable.
