It depends, maybe,
The short answer is yes.
A more accrate answer is yes but the safe capacity of the transformers in parallel may be less than the safe capacity of one of them by itself.
The transformer KVA ratings must be adjusted to the same %impedance base.
For example, if a transformer of 6% impedance is to be paralleled with a transformer of 3% impedance, the transformer with the higher % impedance should be re-rated to 3%.
A 1000 KVA transformer rated at 6% impedance woud be a 500 KVA transformer rated at 3% impedance. If the other transformer is rated at less than 500 KVA, the safe loading on the combination will be less than 1000 KVA.
What are your KVA ratings and %impedance ratings?
Transformers may have the same %impedance but different %regulation. This may cause slight errors that are generally ignored.
