What are the consequences of parallel operation of transformers that do not meet the parallel operation conditions?

When transformers operate in parallel with different transformation ratios, circulating current will be generated, which will affect the output of transformers. If the percentage impedance of transformers does not match and the transformers operate in parallel, the load cannot be distributed according to the capacity ratio of transformers, and the output of transformers will also be affected. When the connection groups are different, the transformer will have a short circuit fault.
