Auxiliary Power Transformer
(OP)
Are there any special reccomendations to use wye conection instead of delta conection to primary winding of an auxiliary power transformer direct conected to a busbar voltage hidrogenerator ? What happens if I use delta conection ?

This is a common occurrence for standby transformers at power plant that have a station service transformer connected to the generator leads. If both are delta-wye, one of these has to have phase shift reversed.
I'd go with delta-wye if you can work it out.
